GYA series hydraulic safety valve overview

1. The hydraulic safety valve is a safety backup device for the (flap-type) breathing valve. Its inhalation and exhalation action pressure is slightly higher than that of the (flap-type) breathing valve. Once the breathing valve fails or works in winter When the flap is frozen, the liquid seal of the hydraulic safety valve is destroyed to protect the oil tank from damage.

2. The hydraulic safety valve is installed on the top of the oil tank and used in conjunction with the breathing valve.

3. Control pressure: +56 mm water column to -50 mm water column.
