    High and low pressure safety valve A11F25C

    The safety valve plays a safety role in the system. When the system pressure exceeds the specified value, the safety valve is opened, and a part of the gas / fluid in the system is discharged to the atmosphere / pipeline, so that the system pressure does not exceed the allowable value, thereby ensuring that the system does not cause an accident due to excessive pressure.

    Spring type micro-starting safety valves

    The opening and closing action of the spring safety valve is based on the change of the medium pressure at the inlet end and the spring pre-tension force to automatically open and close the valve core. When the medium pressure rises to a level where the lifting force is greater than the spring preload force, the valve core automatically opens against the spring preload force, releasing excess medium and reducing the internal pressure. Due to the spring force, when the internal pressure drops to safety When the value is reached, the spool will close automatically and the discharge will stop. Spring micro-opening safety valve has the characteristics of simple structure, good sealing performance, accurate opening pressure, large discharge capacity, small back seat pressure difference, and easy adjustment.

    Fluorine safety valve

    Adjustment of set value ◆ Connect the switch terminal of the controller to the power supply control circuit of the compressor motor. The controlled gas is introduced into the controller bellows chamber. ◆ Rotate the setting value adjustment lever to make the pointer indicate on the scale of 0.5MPa, this value is the lower switching value. ◆ Turn on the power to make the compressor work and the gas pressure will rise. Repeatedly adjust the switching difference knob to make the controller switch when the pressure rises to 0.6 MPa (up switching value).

    J1A42F-24C full open safety valve

    The opening and closing action of the spring safety valve is based on the change of the medium pressure at the inlet end and the spring pre-tension force to automatically open and close the valve core. When the medium pressure (internal pressure) rises to a level where the lifting force is greater than the spring preload force, the valve core automatically opens against the spring preload force and releases excess medium to reduce the internal pressure. When the pressure drops to a safe value, the spool automatically closes and the bleeding stops.
