Brass Pressure Relief Valve
Precautions for using brass pressure reducing valve works
1. Pay attention to the direction of water flow when installing;
2. Adjust the opening of the needle valve: first tighten the needle valve in a clockwise direction until it cannot be screwed, and then return it half a turn to between two turns. After adjustment, the knob cannot be changed at will;
3. Loosen the nut on the pilot valve and turn the screw on the pilot valve to adjust the pressure during pressure relief. When adjusting, the screw on the pilot valve should be withdrawn, start the water pump to let the water drain from the pressure relief valve, and gradually screw in the adjusting screw to gradually increase the pressure of the pump until the required pressure is set. Tighten the lock after adjustment Tighten the nut. If it is under high pressure, the pointer may swing or turn the needle valve knob in a clockwise direction, but it cannot be screwed down;
4. Change the flow rate by other bypass pipes or water supply network and observe whether the pressure relief pressure is stable;
5. If there is a control failure, first check whether the small filter of the control pipeline is blocked, and then check whether the pipeline is unblocked, whether the main valve and pilot valve diaphragm are broken, and whether the gasket is damaged, etc., if any, replace it.
