1.0 Physical Description And Operation Of Equipment

1.1 Globe Valves

These valves are primarily designed for tight-shutoff and throttling service where control of the velocity of the fluid is

necessary. If required, they can also serve as a means of isolating a portion of a system. Their use however, is limited
to those systems where head losses are not critical as the internal flow passage creates a pressure drop across the
valve. With the disc in the full open or any intermediate position, the fluid is allowed to flow through seat area at a rate
determined by the position of the disc. With the disc in the closed position, the force of the stem provides a mechanical
seal between the disc and seat and effects a shutoff at the valve.

The Series 800 globe valve is a precision cast body and yoke assembly. It is an investment casting and offers smooth

flow passages for minimum pressure drop and minimum turbulence.

Series 800 globe valves are provided with a quick-open style disc to provide throttling flow characteristics.

Series 800 globe valves are supplied with handwheel actuators. To operate these manual valves, turn the handwheel in

a clockwise direction for closure and counter clockwise for opening.

2.0 Design Conditions

Refer to the applicable drawings in Section 11 of this manual.

3.0 Operating Conditions

Refer to the applicable drawings in Section 11 of this manual.

4.0 Test Conditions

4.1 Each valve covered by this manual has received the following hydrostatic tests:

4.1.1 Shell hydrostatic test at 1.5 times the 100°F pressure rating.

4.1.2 A disc closure test at 110% of the 100°F pressure rating.

4.0 Test Conditions

4.1.3 A seat leakage test at 110% of the valves specified maximum "delta P".

4.1.4 A backseat leakage test at 110% of the 100°F pressure rating.

4.1.5 A packing test at 110% of the 100°F pressure rating.

5.0 Operating Precautions And Limitations

5.1 Maximum hydrostatic test pressure shall not exceed the values imposed by the ASME Code, Section III.

6.0 Installation Instructions

6.1 Lifting and Handling Requirements and Limitations

6.1.1 Good judgment should be exercised in selecting a lifting device that will safely support the unit's weight.

6.2 Installation

6.2.1 Although the valves have been shipped in a clean condition, prior to installing the valves, examine the lines
and the valve ports for foreign matter and clean them thoroughly if they have been exposed to the elements.
(BEFORE CLEANING IN THIS FASHION, CHECK AT THE SITE TO SEE IF A SPECIFIC CLEANING
PROCEDURE SHOULD BE FOLLOWED.) Open the valves fully and flush them out with water if possible;
otherwise blow them out with air or steam.

In performing this cleaning procedure, the ports should be vertical, the stem horizontal to assure complete

removal of all matter which might have accumulated during storage.

6.2.2 Ensure that there is no line sag at the point of installation. Eliminate any pipeline deviation by the proper use of
pipeline hangers or similar device.

6.2.3 Where possible, install the valves with the stem vertical.
