Valve Selection

2.1 Introduction

Flowserve Vogt Valves, is a world leader in the manufacture of forged steel, alloy steel, and stainless steel gate, globe and check valves. Since Vogt valves are used for a variety of applications and in various operating environments, it is reasonable to expect that the performance of a valve will reﬂect upon its selection and suitability for the speciﬁc service as well as proper installation and maintenance. As a long time member of the Manufacturers Standardization Society (MSS) of the Valve and Fitting Industry, Inc., Vogt engineers have participated in the development of MSS SP 92, MSS Valve User Guide. This guide was developed to recognize and offer recommendations to correct operating problems involving industrial valves that were not properly selected for the intended service, or were adversely affected by improper handling, installation, operation, or maintenance.

The purpose of this publication is to supply detailed information that relates speciﬁcally to selection, storage, installation, operation, and maintenance of Vogt gate, globe and check valves.

Flowserve Vogt Valves endorses the recommendations outlined in the following source as it pertains speciﬁcally to the selection, shipping, storage, installation, operation and maintenance of Vogt gate, globe and check valves:

2.5 Pressure/Temperature Rating

Proper selection of the pressure/temperature rating of the valve shall meet service requirements. If the valve application involves temperatures above 100°F (38°C), then the valve pressure rating at the service temperature must be veriﬁed to meet the requirements of the application.

If system testing will subject the valve to a pressure in excess of its working pressure rating, then the intended testing pressure and a statement explaining whether the test pressure is through the opened valve or a differential across the closed valve, should be included in the purchase speciﬁcation.

Source Reference for Vogt valves pressure/temperature ratings

ASME B16.34 Valves, Flanged, Threaded, and Welded End VVACT0000, Vogt Catalog.

2.6 Bending Strength

Piping systems are subject to mechanical constraints at ﬁxed support points such as rigid nozzles, anchors, etc. Cold springing at assembly, system temperature changes, together with gravity, possible inertia loads, landslides, non-uniform subsidence in buried lines, etc., all potentially affect the bending moment at various points in the piping.

Valves are also subjected to the bending moment occurring in the adjacent pipe that is in addition to the normal pressure loading. Bending loads can cause deformation in valve bodies that can be detrimental to valve performance. It is therefore a recommended design practice to avoid locating valves at points of large bending loads.

Class 150, 300, 600 and 800 Vogt valves have bodies with a nozzle section modulus (I/C) greater than Schedule 80 pipe. Class 1500 Vogt valve bodies have I/C section modulus greater than that of Schedule 160 pipe. If the connecting pipe meets the above or has a lesser wall thickness, it is expected that the piping would be the weaker element when connected to a Vogt valve and exposed to a bending load. If the schedule pipe to be used with the Vogt valves are greater than the above (pipe has a heavier wall thickness), the purchase order shall denote this and Flowserve will provide an I/C section modulus calculation for the valve body/adjoining pipe to ensure the piping is the weaker element, or will advise customer otherwise.

2.7 Fire Safety

Flowserve Vogt Valves all metal-seated gate, globe and check valves come standard with ﬂexible graphite packing and gaskets and are of a ﬁre-safe design. If these valves are supplied with low melting point packing, or gaskets, such as ﬂuoropolymer or elastomeric seals for sealing, the ﬁre-safe design and full shell pressure/temperature ratings are sacriﬁced.

The purchase order should indicate when the customer requires ﬁre-safe designs.

2.8 Pressure Surge

Closure of a valve in a ﬂowing ﬂuid line causes the velocity of the ﬂuid to be reduced to zero. If the ﬂuid is a relatively incompressible liquid, the inertia of an upstream column produces a pressure surge at the valve whose magnitude is inversely proportional to the time required for closure. The surge pressure is also proportional to the length of the upstream ﬂuid column and the ﬂuid velocity prior to closure initiation. If the application involves a long upstream line, a long downstream line, high velocity, or rapid closure, singly or in any combination, the possibility of an unacceptable pressure surge should be investigated.

Also to be considered are condensation-induced pressure surges which occur when a ﬂuid velocity change is caused by rapid condensation or when a slug of water is accelerated by contact with steam. An example would be when condensate collects on one side of a closed valve that has steam on the other side, then opening the valve will cause collapsing steam voids, sharp pressure surges and acceleration of condensate slugs. Condensation-induced pressure waves can result in pressure pulses that are signiﬁcantly higher than those produced by a sudden valve closure. In such events, non-shock rated gray iron valves installed in steel piping systems are particularly vulnerable to catastrophic failure. Traps are required to prevent condensate accumulation and “blow-off” valves located at the low point in the system are needed to ensure condensate drainage. Operation and maintenance personnel must be aware of the function of these devices in relationship to the “shut-off” valve operation and the necessity for their being in proper working order.

2.9 Throttling Service

Flow control (throttling) valves may be subject to extreme ﬂuid turbulence that may create a high-energy conversion within the valve and associated piping system. High noise levels usually indicate this energy conversion, either by cavitation of liquids or by shock waves from gases.

Therefore, it is possible to damage the valve and piping system when the throttling of liquid ﬂow results in severe and continuous cavitation conditions. Likewise, with gas ﬂow under severe throttling conditions, shock waves can possibly result in damage to the system.

Vogt “ﬂow control valves” should be used when the user requires true ﬂow regulation. Flowserve Vogt Valves should be consulted on proper valve selection for throttling and/or ﬂow control applications.

2.10 Temperature Changes

Forged steel expands and contracts with rising and falling temperatures, and in general, an increase in temperature results in a decrease of mechanical strength that is regained on return to a lower temperature. A temperature gradient in a steel part may impose signiﬁcant thermal stresses or deformity with a possible negative effect on valve performance.

Frequent temperature cycling may result in development of thermal stress fatigue. Any one or a combination of the following increases this possibility:

An increase in temperature range, level, rate of change, an

increase in the metal section thickness, or number of cycles.

Thermal cycling has been determined to increase the tendency

for stem seal leakage.

2.11 Trapped Pressure

When a closed valve containing liquid is heated (e.g., from process condition, radiation or solar heating) the cavity pressure will increase due to volumetric expansion or vaporization of the liquid. Conversely, cooling an un-drained cavity below the freezing point may also result in volumetric expansion of the media. These types of expansion can result in extremely high pressures in the valve.

A bonnet cavity relief can be added to Vogt gate valves when the user determines that the conditions for over-pressurization of the “locked-in bonnet cavity” exist. Globe and check valves do not have a “locked-in volume” when the valves are closed and are not subject to this trapped pressure.

2.12 Material Compatibility

It is signiﬁcant that forged valve materials and lubricants used in construction be chemically consistent or compatible with the connecting piping system components, line ﬂuids, applications and the environment. Flowserve, or the system design engineers, should be consulted whenever there appears to be reason for such concern.

Flowserve Vogt Valves has construction procedures for valves used in various applications, one being “food service”. These procedures ensure that valve materials, and lubrication used in manufacture are compatible with food standards. Flowserve should be consulted on proper valve selection when applications require special cleanliness, materials and/or lubricants.

2.13 Operating Effort

Vogt valves are designed to require a reasonable amount of physical effort applied to a handwheel to open or close at rated working pressure. Maximum handwheel torques at maximum pressure ratings are listed in Section 5 of this manual.

Shipping And Storage

3.1 Introduction

Flowserve recognizes the importance of maintaining the as-built condition of valves, and has prepared this section to call attention to important considerations in the handling of valves prior to installation.

Vogt forged steel valves are tested and shipped ready for installation. These valves are well-designed, fabricated under an ISO 9001 Quality Program, and inspected and tested to provide years of satisfactory service. Vogt valves can withstand a variety of damages caused by impact, shock or incursion of detrimental materials after installation. However, the intermediate period between the factory production tests and the installation in the end-user’s pipeline may involve exposure to damage during shipping that may adversely affect the subsequent service performance of the valves.

Vogt valves are packaged to rigorous procedures, depending upon end-user speciﬁcations, and are padded and boxed for full protection during shipment to our customers.

Attention to the recommendations and cautions here will provide enhanced assurance of a satisfactory valve when installed.

3.2 Handling

Appropriate care in handling valves should be complementary to the degree of protection provided in preparation for transport. A basic consideration in handling valves should be to avoid damaging the protection provided for shipment. An obvious general rule is that valves should never be thrown or dropped. It is advisable to keep the valve(s) in the shipping containers until the valve is to be installed.

Vogt valves are carefully made from selected materials to give long, trouble-free service when properly installed in applications for which they were designed. Proper care and maintenance in the ﬁeld can contribute signiﬁcantly to maximum performance.

The care the valve receives between the time it is shipped by the manufacturer and installed in the piping system is important. During this period, the valve can be handled many times and can be kept in storage for long periods. Industrial valves are not delicate, but they are mechanical devices, which should be treated as such and handled with care.

FCD VVENIM2000-02 Forged Steel Gate, Globe and Check Valves 15

Flow Control

Vogt Valves

Flowserve always provides valves with appropriate end covers to protect the end connections and to prevent foreign material from entering the valve. In addition, small valves are shipped in sealed cartons while larger valves are usually palletized. If at all practical, keep the valves in the cartons or on the pallets with end covers in place until ready to be installed. Storing the valves off the ground and indoors is always preferable. When stored outside, valves should be off the ground and protected by a weatherproof cover.

3.3 Storage – Short Term

Recommendations

Following acceptance testing and inspection at the factory, Vogt products are moved to storage. During movement to storage, Vogt products are protected from rain and snow, stored in a building that is provided with uniform heating and cooling control, and outdoor storage is not permitted.

Store products away from exposure to the outside environment, airborne contaminants, acceleration forces, and physical damage.

Store products within a ﬁre-resistant, weathertight, and wellventilated building or equivalent enclosure. This area should be situated and constructed so that it is not be subject to ﬂooding; the ﬂoor should be paved or equal, and well drained.

The storage area should be located and constructed so that it will not be subject to ﬂooding. The ﬂoor should be paved or equal and well drained.

Place individual valves or other product separated from its shipment pallet and/or box on pallets or shoring to permit air circulation. Keep the valve ﬂow ports sealed with the Vogt-supplied plugs and/or covers.

If outdoor storage is unavoidable, support products off the ground or pavement, protected by a watertight enclosure.

Weatherproof covering, when used for outdoor storage, should be a ﬂame-resistant type of sheeting or tarpaulins. Place them so as to provide drainage and to ensure air circulation to minimize condensation. Tie them down to prevent moisture from entering laps and to protect the covering from wind damage.

Since Vogt Valves’ packing and gaskets have an indeﬁnite shelf life, valves may be removed from storage and installed without further preparation. This procedure shall be supplemented with valve motor and/or air cylinder manufacturer’s storage recommendations for Vogt valves modiﬁed with motor or air cylinder valve actuators.

Place items on pallets or shoring to permit air circulation. This area should be provided with uniform heating and temperature control or its equivalent to prevent condensation and corrosion.

Do not remove valve end protectors unless necessary for inspection and installation.

3.4 Storage – Long Term

Recommendations

Keep Vogt Valves products in the as-shipped pallets and/or boxes as long as practical. Do not remove valve end protectors unless necessary for inspection and installation.

Upon receipt, inspect pallet and/or boxes for handling damage and/or exposure to rain and/or ocean spray. Report damage to the transport agent.

Store the pallets and/or boxes for protection against the weather. Ideally products should be kept indoors with actual storage temperature always higher than the dew point.

The storage area should be a ﬁre-resistant, tear-resistant, weathertight, and well-ventilated building or equivalent enclosure.
