The ZMQ type pneumatic diaphragm cutting valve (short for cutting valve) is the actuating unit in a pneumatic unit combination instrument. It directly controls the cutting and flow of the regulated medium according to the signal output by the regulating instrument, achieving automatic control of parameters such as pressure, flow rate, or hydraulic pressure. The main difference between the cutting valve and the regulating valve is that the former is used for two-position discontinuous regulation, while the latter is used for multi-position continuous regulation.
This product features a simple structure, easy operation, compact size, and lightweight design. The valve body is innovatively designed with low flow resistance, large capacity, and excellent sealing performance, capable of fire and explosion resistance. The sleeve-type cut-off valve employs a balanced valve core structure, enhancing the allowable pressure difference. The valve core offers both soft and hard sealing options, allowing for flexible selection based on application requirements. Consequently, it is widely used in the automatic and remote control systems of various industrial sectors, including petrochemical, chemical, metallurgy, power, light industry, and textile production.
