Selection between high-pressure direct-acting pressure relief valve and high-pressure angle valve?
Thread Content
Our unit is equipped with a high-temperature, high-pressure wax oil pump with a flow rate of 20 tons per hour. A high-pressure angle valve is installed at the pump outlet to return the fluid to the tank (used during normal operation), while a pressure-reducing direct-through valve is used for returning the fluid to the tank as well (used in idle mode, that is, when all fluid needs to be returned to the tank). Why is this necessary? Can’t we use just one type of valve? We would appreciate some explanations
It’s the minimum flow line; the pressure is high, so open it first when starting!
In ordinary high-pressure pumps, a high-pressure angle valve is installed at the outlet to return fluid to the extraction tank, but in our pump, the angle valve and the pressure-reducing direct-through valve are both installed at the pump outlet
