TOP GUIDE SINGLE SEATED TYPE

The design of Quick Change type control valves are designed for low and medium duty service. The compact valve, simple construction having low pressure loss, allows large flow capacity rangeability, and high accuracy flow characteristics.

It is available with bellows seal, extension, fin, jacket bonnet. The flow shut-off performance complies with the JIS, ANSI standards. Standard combined actuators are multi-spring diaphragm actuator.

FEATURES

· Reliability
The screwed-in seat ring on a tapered seating to minimize fluid leakage and erosion at the back of the seat ring.
· Valve plug stability
Two rugged and widely spaced packing box guide bushings stabilize and guide the valve plug at all point in its travel range to minimize vibration, mechanical noise, and trim wear.
· Application flexibility
The design of valve accepts a full range of equal percentage, linear, and quick opening valve plugs designed to handle a wide range of flow requirements. Restricted-capacity trim can be easily replaced with full-capacity trim. Hardened trim materials are available to increase trim life and improve performance.
· Economy
The design of valve delivers outstanding performance over an extended lifetime and is economical in cost of equipment, installation, and, maintenance.
