Single seat control valve

This kind of valve is the control component of automatic control system and remote control system, which is used to control the flow of liquid and gas. The design of this series of control valves reflects the latest trend of world technology, and according to the requirements of ISO 9001 quality assurance system, it is processed by high performance and high precision machining tools. These products have been recognized and praised by customers. Due to the wide range of materials and the diversification of design forms, these valves can be applied in different industrial fields. It is suitable for petroleum, chemical industry, electric power, metallurgy, shipbuilding, papermaking, biopharmaceuticals, food industry systems, etc.


Flow characteristics are equal percentage, linear and fast opening.

Valve body materials are cast iron, ductile iron, carbon steel, stainless steel and alloy materials.

The inner parts of the valve are made of stainless steel and alloy.

Valve internals can be hardened by heat treatment and hardened by surfacing Ti-Lai alloy to increase hardness and corrosion resistance.

Balancing plug can be used to reduce unbalance force in high pressure situations.

Corrugated pipe sealing valve cover and TA-Luft packing can prevent corrosion or leakage of toxic media;

Extended cover and graphite packing can be used in high temperature medium.

Seat seals are metal seals or soft seals with leak grades of IV, V and VI.

_Multi-spring thin film actuator, can install up to 24 springs, the maximum spring pressure is 1.8-3.8 bar;

_The spring pressure range can be adjusted without changing the spring or adding other parts.

Exchange of positive and negative actuators can be realized without replacing or adding other parts.

In addition to pneumatic actuator, it can also be equipped with electric actuator and additional handwheel.

Valve positioner, filter relief valve, solenoid valve, limit switch, air lock valve, etc.

Other annexes;

According to the 94/9/EC-ATEX regulation, it can be applied to the following special media: oxygen, hydrogen, gas.

Fuel, low temperature medium (liquid oxygen, liquid nitrogen), acid gas containing H2S, explosive gas, etc.
