Product use ZCRB series normally open gas emergency shut-off valve is a new type of safety supporting device for gas pipeline engineering. The main applications are as follows: 1. Connected with flammable gas leakage monitoring instruments. When the instrument detects a flammable gas leak, it automatically closes the main gas supply valve quickly and cuts off the gas supply.
Product overview ZSQ pneumatic piston shut-off valve (referred to as piston shut-off valve) is the execution unit in the pneumatic unit combination instrument. It receives the signal from the regulating instrument to control the cut-off of the fluid in the process pipeline, or to switch the flow channel. This product has large operating force, novel valve body design, small flow resistance, and rated flow rate.
The fluid in the art pipeline is cut off and connected or the flow channel is switched. This product has the advantages of large operating force, novel valve body design, small flow resistance, large rated flow coefficient, large allowable pressure difference, and excellent sealing performance. Therefore, it is widely used in automatic control and remote control of production processes in industrial sectors such as petroleum, chemical industry, metallurgy, electric power, and textile.
Product overview The ZMQ pneumatic diaphragm shut-off valve uses a multi-spring actuator and three vertical posts connected to the adjustment mechanism. The overall height can be reduced by about 30% and the weight can be reduced by about 30%. · The valve body is designed as a low-flow resistance flow channel with the same cross section according to the principle of fluid mechanics, and the rated flow coefficient is increased by 30%. ·valve
