Sliding Diaphragm Gate Control Valve, 1/4-2 IN, Ductile Iron
Key Specifications / Features
Hits: 2
Introducing our line of pneumatically-operated diaphragm control valves, featuring multiple spring actuators and precision sliding gate seats for enhanced control and accuracy. Available in sizes from 1/4 inch to 2 inches (DN8-DN50) with PN10 and 150 LB pressure ratings, these valves are made from durable ductile iron, ideal for precise flow control in diverse industrial applications. Optionally, they can be equipped with side or top-mounted positioners to minimize hysteresis, ensuring the valve stem position aligns precisely with the control signal for optimal performance.

Cv (Kv): up to 30 (up to 26)
Action: Direct (air signal closes valve), Reverse (air signal opens valve)
End Connections:
Threaded (NPT, BSPT, BSPP-through 2 Inch sizes/DN50)
ANSI Flanges (150#, 300#)
DIN Flanges (PN10/16, PN25/40)
Service: Steam, Water, Oil, Gas, Air and Chemicals
Features & Benefits:
1. The enclosed multi-spring actuator reduces deadband and allows field reversibility without special tools.
2. The compact, straightforward design facilitates quick installation and maintenance.
3. Stem packing offers four times the depth of stem travel, enhancing leak protection.
4. Sliding gate seats ensure straight-through flow, reducing turbulence and noise.
5. Short stroke ensures rapid response and precise regulation.
6. Easily interchangeable CV's.
7. Provides tight shutoff for reliable operation.
