Overview

GE’s Masoneilan 39004 Series High Performance Butterfly Valve (HPBV) is designed for exceptional performance, application flexibility and long service life. This automatic throttling control valve offers benefits such as enhanced sealing, double offset operation, excellent flow characteristics, accurate positioning, and dynamic operation. The 39004 Series features seal designs for soft seal and fire-safe configurations. Combined with the Masoneilan 96/97 Series actuator, the 39004 Series High Performance Butterfly Valve package delivers years of dependable performance in demanding applications.

Features

The 39004 Series High Performance Butterfly Valve incorporates two main features that differentiate it from conventional swingthrough butterfly valves – a seal ring and double offset (eccentric) operating principles for the seal and the shaft.

The use of a seal ring eliminates the inherent problem of high sealing forces due to interference fit and the resultant high wear rates caused by liner scraping and scuffing. Additionally, the dynamic, pressure-assisted seal design results in ASME Class VI shutoff rates available throughout the full range of ASME Class 150, 300 and 600 ratings.

The double offset (eccentric) operating principles shown in Figure 1, apply to both the seal offset, in which the seal ring centerline is offset from the shaft centerline, and shaft offset in which the shaft centerline is offset from the valve centerline. The design allows the disc to lift from the seal quickly due to the camming rotation with respect to the valve/seal centerlines.

These two features contribute to an exceptional high performance butterfly valve that offers many benefits:

Excellent Flow Characteristics

The offset disc design provides an approximate equal percentage flow characteristic through its full travel of 90° rotation yielding a Cv ratio of 100:1.

Precise Positioning

Extra heavy shafts with keyed ends for actuator mounting offer accurate positioning without lost motion or backlash.

Cost Savings

The design of the 39004 Series reduces operating torques. As a result, smaller actuation packages are required to operate the valve. Maintenance costs are also reduced through the modular seal design.

Long Service Life

The PTFE-lined low-friction bearings provide excellent service life while resisting corrosion and distortion from high temperatures and mechanical loading.

Application Flexibility

The Masoneilan 39004 Series is suited for a wide range of control applications including corrosive chemicals, water, gases, acids, hydrocarbons and other process fluids.

Long Seal Life

The double offset operation lifts the disc from the seal quickly to minimize sliding contact and friction. The result is reduced seal wear as well as lower breakaway and seating torque requirements. This design has been extensively tested maintaining zero leakage shutoff performance throughout the entire life-cycle endurance test.

Fast and Dynamic Operation

Double offset operation eliminates disc-to-seal friction throughout the operating range resulting in fast response to input signals. Also, the disc tends to move in the direction of flow which enables the valve and actuator to maximize allowable operating pressures.

Ease of Installation and Maintenance

The reduced size and weight of the 39004 Series valve compared to typical rotary and globe products enables fast and easy installation into the pipeline. The seat design also supports easy maintenance by allowing the removal and replacement of the seat retainer without modifying the disc or stem.

Features - Seat Design

Energized Soft Seat Design

The Masoneilan 39004 High Performance Butterfly Valve Includes unique valve seal designs for soft seal and fire-safe configurations.

The 39004 Series soft seal design provides a bi-directional bubble tight shutoff (zero leakage) through the use of a patented seal. This unique, two-part seat assembly includes a resilient energized system that is completely encapsulated by the seat. Advantages include:

•

Fire-Safe Seat Design

The fire-safe seal design incorporates two seal designs which function together to seal off pipeline flow. In normal operation, the soft seal provides a bi-directional “bubble tight” shutoff (zero leakage) across the full range of rated pressures and temperatures. The metal seal offers bi-directional shutoff in the event of a fire in conformance to industry fire-safe requirements.

With little or no pressure, the fire-safe seal creates a self-energized seal against the disc. Higher line pressures act on the geometry of both seals to dynamically load them against the disc creating higher sealing forces in either direction. If excessive heat destroys the resilient seated materials, either partially or completely, the seat provides a constant metal-to-metal backup seal.

In real fire conditions, line pressure is immediately reduced and the entire area is hosed down. The resulting pressure drop and rapid cool down causes many valves to fail. The 39004 Series firesafe design does not rely on line media pressure to seal; therefore, the valve offers superior low pressure performance compared to competitive designs. The Inconel alloy seat offers better corrosion resistance and greater strength than the stainless steel seats commonly used.

This fire-safe design has been tested and certified to API 607, 5th edition fire-safe standards.

Metal Seat Design

An optional metal to metal seat is available for applications requiring erosion resistance and higher operating temperatures. The inconel 718 seat design provides better than class IV shutoff in both flow directions.

This design also comes with a nitrided stainless steel disc for increased mechanical cycle life. Special metal seat constructions are available to handle those applications above 500ºF (260ºC).

Features - Actuator

Series 96/97 Pneumatic Actuator

Masoneilan Series 96/97 Pneumatic Actuator is a rack and pinion, opposed-piston actuator available in a double acting option for 90°, 135° and 180°rotations as well as a spring return option for 90° rotation. It is ideal for use on the Masoneilan 39004 Series High Performance Butterfly Valve in either automated on/off or throttling service. The Series 96/97 is available in nine different sizes for application flexibility. Plus, the low friction design makes the Series 96/97 well suited to handle offset loads to the gear and output shaft assembly. Some of the key features include:

• QQ Integral Passages – Reduces cost of external tubing.

•

QQ Piston Guides and Rings – Pr
