Product details
GYA hydraulic safety valve is a safety backup device for (valve type) breathing valves. Its suction and exhalation action pressures are slightly higher than those of (valve type) breathing valves. Once the breathing valve fails or its valve freezes in winter, the liquid seal of the hydraulic safety valve is destroyed, thereby protecting the oil tank from damage. The hydraulic safety valve is installed on the top of the oil tank and used in conjunction with the breathing valve. Control pressure:+56mm water column to -50mm water column.
