500X Holding Pressure /Relief Pressure Valve
Place of Orign :China
Product name: 500X Holding Pressure /Relief Pressure Valve
Structure And Purpose: 500X Pressure Discharge & Sustain Valve is used in the pipeline system to prevent of surpassing pressure or to keep the pressure of it, to reduce the water hammer’s shock after the pump is closed and also used as a water hammer remover in the large water supply system. A self cleaning filter screen is placed on the inlet of the valve’s control system, which stops the suspension grains of the bigger specific gravity and diameter from going into the system by means of the bigger specific gravity of the fluid to ensure the main valve’s water supply pressure at the upstream at the set value, and to get the system circulated smoothly without any resistance. This valve features by sensitive open-close, safety, reliability, stable motion and long duration. |
