The hydraulic safety valve is an important attachment to protect the safety of oil tanks on the top of the oil tank.When a mechanical respiratory valve fails, the hydraulic safety valve can replace the mechanical respiratory valve for exhaust or deflation.
The role of hydraulic safety valve
1. The hydraulic safety valve is a safety spare equipment for the (live petal) respiratory valve. Its inhalation and exhalation of the action pressure is slightly higher than the (live petal) respiratory valve. Once the respiratory valve is failed or in winterWhen the petals are frozen, the liquid seal of the hydraulic safety valve is destroyed to protect the oil tank from damaging.2. The hydraulic safety valve is installed on the top of the oil tank with the breathing valve.

Principle of hydraulic safety valve
The working principle of the hydraulic safety valve is: when the pressure is too large, it will be turned on and the hydraulic oil will be placed back to the oil cylinder.
