Shut off valve - pneumatic shut off valve - electric shut off valve - hydraulic shut off valve
The shut-off valve is composed of ball valve, globe valve, regulating valve, pneumatic, electric, hydraulic actuator and electronic accessories. The products include pneumatic cut-off valve, electric cut-off valve, hydraulic cut-off valve and gas cut-off valve. The power/gas source of the actuator is controlled by electronic components to control the cut-off, connection or switching of fluid in the process pipeline.
The cut-off valve can only be fully opened or closed, and cannot be used to regulate pressure or flow. The emergency cut-off valve is a fire safety protection device, mainly for the automatic valve that can be remotely controlled in case of leakage or leakage of combustible gas/liquid and irritating toxic media.
Pneumatic shut-off valves and electric shut-off valves are widely used in such industries as crude oil exploitation, natural gas, chemical industry, electric power, medical treatment, food, water treatment, fire protection, environmental protection and other mechanical equipment.
Main applications of hydraulic cut-off valve:
The liquefied gas filling station and liquid ammonia storage tank are used together with the manual oil pump. The hydraulic cut-off valve is a normally closed cut-off valve. The hydraulic pressure of the manual oil pump is used to push the piston of the cut-off valve up and down to open and close, which is used as a valve for short-term loading and unloading.
Main applications of gas shut-off valve:
1. It is connected to the central fire alarm system of high-rise buildings. In case of fire in the building, the control system will supply power to the cut-off valve coil, and the gas cut-off valve will automatically cut off the gas supply of the pipeline in the building to prevent the occurrence of gas deflagration.
2. It is connected with the combustible gas leakage monitoring instrument. When the instrument detects the combustible gas leakage, it will automatically and quickly close the main gas supply valve, cut off the gas supply, and stop the occurrence of malignant accidents in time;
3. ZCRB gas emergency cut-off valve is set in the gas supply pipe network of the city or factory, which can be centrally controlled in the central control room, and the pipeline gas supply at the accident site can be remotely and remotely closed.
4. It is connected with the limit temperature and pressure safety controller of the thermal equipment. When the temperature and pressure of the detection point in the equipment exceed the set limit value, the gas supply valve will be automatically and quickly closed to stop the fuel supply;
Shut off valve It can be matched with domestic or imported accessories, and its brands include: Yadeke pneumatic triplet, Japanese SMC/50-VFE3130-5t-02 explosion-proof solenoid valve, American ASCO/EF8551G401MO explosion-proof solenoid valve, Honeywell BXA3K-1A explosion-proof limit switch/travel switch, Japanese SMC/AW20-02B-C-A air filter pressure reducing valve, Omron mechanical induction travel switch.
