所屬類別：Quick high performance pneumatic control valve

KLP series pneumatic control valve is driven by compressed air source to the cylinder as the actuator,, and with the help of electrical valve positioner, converter valve, the valve attachment to drive the valve, switch or proportional regulator, receive to complete the conditioning medium pipe control signal automatic control system industry: all kinds of process parameters of flow, pressure, temperature etc.. Pneumatic control valve is characterized by simple, rapid response, and intrinsically safe, no need to re take the explosion-proof measures.

KLP series pneumatic control valve shape, light weight, high performance, large capacity, is in line with the IEC standard of a new generation of valve products. The production process system which is suitable for general fluid medium and process conditions. The pneumatic spring film executive body and low flow resistance of single seat valve, new actuator, light weight, high's alignment is simple, novel compact structure, smooth flow, with large flow coefficient.

KLP series pneumatic control valve operation is stable, reliable operating characteristics, tiny seat leakage, accurate flow characteristics, wide adjustable range etc.. It gets the control effect of high quality in a wide range of users with unique advantages.
