First, The Pneumatic Three-way Shut-off Valve Overview
Pneumatic three-way shut-off valve with a top-oriented structure, with a multi-spring actuator. With a compact structure, light weight, sensitive action, the fluid channel was S streamlined, the pressure drop loss is small, the valve capacity is large, easy disassembly and so on. The shut-off valve accepts the signal from the regulating instrument, cuts off, turns on or changes the flow of the medium, and automatically controls the process parameters such as pressure, flow rate, temperature or level. Widely used in petroleum, chemical, metallurgical, power, light industry, textile and other industrial sectors of the production process of automatic control and remote control system.        This series of products are thin film, piston type two. The body structure has a single seat, sleeve, two-seat (two three links) three, sealed with a sealed seal and bellows seal two, the product nominal pressure level PN10,16,40,64 four, nominal caliber Range DN20 ~ 200mm. Applicable fluid temperature from -60 ~ 450 ℃. The leak level is grade IV or grade VI. The traffic feature is fast.

Second, Pneumatic Three-way Shut-off Valve Product Features
1, Cut off the valve with a multi-spring actuator and adjustment mechanism connected with three columns, the whole height can be reduced by about 30%, the weight can be reduced by about 30%. 2, the valve body according to the principle of fluid mechanics designed to equal section low flow resistance flow channel, rated flow coefficient increased by 30%.
3, The trim parts are tight and soft seal two kinds of tight type for the welding carbide, soft seal for the soft material production, close the sealing performance.
4, Balanced trim, to improve the allowable pressure difference between the shut-off valve.
5, Bellows seal on the movement of the stem to form a complete seal, blocking the possibility of media leakage. 6, the piston-type executive, the operating force, the use of large pressure.
