    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.

    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.
