PRODUCT INTRODUCTION
1. Description
ZMPQ pneumatic Cutting-off valve driven by the top guided structure, equipped with multi-spring actuator. With a compact, light weight, sensitive, fluid channel S streamlined, low pressure drop, large valve capacity, and easy disassembly. Shut-off valve to receive signals from the adjustment of the instrument, cut, open, or change the media flow, to the pressure, flow, temperature, level and other process parameters or automatic control. Widely used in the production process control in petroleum, chemical, metallurgy, electric power, light industry, textile and other industrial sectors and remote control systems.
This series of products are film, piston two. Body structure with a single seat, sleeve, two-seater (two-way) three, there are two forms of packing seals and bellows seal Nominal grade products are PN10, 16,40,64 are four nominal diameter range DN20 ~ 200mm. For fluid temperature from -60 ~ 450 ℃. Leakage Class IV or Ⅵ grade level. Flow characteristics for the quick opening.

3. Features:
Cutting-off valve actuator and multi- spring adjustment mechanism connected with three columns, the entire height can be reduced by about 30 percent , reduce weight by about 30% .
Valve designed according to the principles of fluid mechanics , such as low flow resistance flow channel cross-section , the rated flow coefficient increases by 30%.
Trim part of a tight seal and soft seal type two , tight type of surfacing carbide, soft seal type of soft material, excellent sealing performance when closed .
Balanced trim , improved Xu shut-off valve with pressure .
Bellows sealed to form a complete movement of the valve stem seal , blocking the way out the possibility of media leaks .
Piston actuator , operating force, the use of a large pressure difference .
