Single Seated Control Valve Pneumatic Top Guide Pneumatic Actuator

2"-36" CL150-2500 industrial control valves pneumatic top guide single seat

Standard Features:

With compacted structure, small shape, S-streamline fluid way, small pressure reduction loss, large flow, wide control range, high-precision flow characteristic curve, large guide area of the valve core, good shock resistance, and high performance and reliability, the single-seat control valve has been widely applied. Shutoff conforms to IEC AND DIN standards.
This vave is widely applicable for the process of high pressure, high temperature, and low temperature as well as the requirement of the reliability and leakage rate.

The actuator can be freely changed between the positive and negative actions in the site without special tools, thus to achieve a quickly switching installation of the control valve.

Free-Pipe Pneumatic Actuator Design. With no external gas circuit and gas pipe between the positioner and the actuator, it can eliminate all external leakage ponits, and avoid the external envirinment corrosion.

Design characteristics :

Quick installation of Positioner. Avoid the leakage and damage of the air supply pipe.

This valve equipped with small and light actuator and has the advantage of wide applicaton area, good stablity with low leakage.it’s a good automatic product in pertrochemical and metallurhical etc insudtries.

Technical notes:

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.

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.
