ZMAQ(Q) Pneumatic Three-way Cut-off Valve product details

ZMAQ(Q) Pneumatic Three-way Cut-off Valve overview

ZMAQ(Q) Pneumatic Three-way Cut-off Valve produced and sold by Baigang valve group with top guide structure, equipped with multi-spring actuator. Has the advantages of compact structure, light weight, action-sensitive, S-streamline fluid flow line, small pressure drop loss, valve capacity, easy disassembly. Shut-off valve to accept the signal from the regulating instrument, cut off, open or change the media flow to achieve automatic control of process parameters such as pressure, flow, temperature or liquid level. Widely used in petroleum, chemical, metallurgy, electric power, light industry, textile and other industrial sectors of the production process automatic control and remote control system. This series of products are film, piston two. The valve body structure has a single seat, sleeve, two seats (three two-way) three, the sealing form of packing seal and bellows seal two, the product nominal pressure grade PN10,16,40,64 four, nominal diameter Range DN20 ~ 200mm. For fluid temperature from -60 ~ 450 ℃. Leakage level for the IV or Ⅵ level. Flow characteristics for the quick opening.

ZMAQ(Q) Pneumatic Three-way Cut-off Valve product characteristics

1, Shut-off valve adopts multi-spring actuator and adjusting mechanism to connect with three columns, the whole height can be reduced by about 30% and the weight can be reduced by about 30%.
2, the valve body designed by the principle of fluid mechanics such as cross-section low flow resistance flow channel, the rated flow coefficient increased by 30%.
3, the valve part of the seal has two types of tight and soft seal, close-type surfacing carbide, soft seal for the soft material production, sealing performance when closed.
4, balanced type trim, improve the allowable pressure drop off valve.
5, the bellows sealed type of valve stem to form a complete seal, blocking the possibility of media leakage.
6, piston-type actuator, operating force, the use of large pressure.
