Masoneilan 39004 High Performance Butterfly Control Valves is Low torque, double offset disc improves control performance and reduces seal wear for longer operating cycles and reduced maintenance. Ratings and Connections is Wafer and lug for mounting between flanges: ANSI 150 – 600.Body Materials is Carbon steel Stainless steel. Masoneilan 39004 High Performance Butterfly Control Valves’s Actuator is Model 96/97 pneumatic rack & pinion Model 34 scotch yoke cylinder
Masoneilan 39004 High Performance Butterfly Control Valves have following features:
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.
Excellent Flow Characteristics The offset disc of Masoneilan 39004 High Performance Butterfly Control Valves design provides an approximate equal percentage flow characteristic through its full travel of 90° rotation yielding a Cv ratio of 100:1.
The current estimated useful life period for the 39004 Series control valve is 25+ years. To maximize the useful life of the product, it is essential to conduct annual inspections, routine maintenance and ensure proper installation to avoid any unintended stresses on the product. The specific operating conditions will also impact the useful life of the product. Consult the factory for guidance on specific applications if required prior to installation.
