Delectric Diaphragm Control Valve with Positioiner NPS 2"~48" Class 150~ 2500

Hydraulic control valves are used in many shipboard systems where access to valves is limited or a remote operation is required. This type of valve may be operated from one or more remote stations by a hydraulic control system. There are many configurations of globe, gate, and butterfly hydraulic control valves available for use on shipboard systems.

The valve shown is piston operated globe valve. It is normally held in the closed position by spring tension. When hydraulic pressure is admitted to the underside of the piston the force overcomes the spring tension causing the valve to open.

When hydraulic pressure is released from under the piston the spring acts to force the hydraulic fluid out of the cylinder and back to the remote control station, closing the valve.

A rachet lever is fitted to the valve to permit emergency opening of the valve by hand.

A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Control valves are normally fitted with actuators andpositioners. Pneumatically-actuated globe valves and Diaphragm Valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball, gate and butterfly valves are also used.
