      ZSQ Double Guide Shut-off Valve overview:

      ZSQ Double Guide Shut-off Valve produced and sold by Baigang Valve Group adopts top - guide structure and multi - spring actuators.It has the advantages of compact structure, light weight, sensitive action, S-streamline fluid channel, small pressure drop loss, large valve capacity, convenient disassembly and assembly, etc.The cut-off valve accepts the signal from the regulating instrument, cuts off, opens or changes the flow direction of the medium, and achieves automatic control of the 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.

       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 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.
