Applications

The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment,and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed,that is,by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction. Then rely on the adjustment of the control and regulation system to balance the fluctuation of the pressure behind the valve with the spring force, so that the pressure behind the valve remains constant within a certain error range.

Product Description

1. Purpose and scope

A pressure reducer is designed to lower the pressure in drinking andindustrial water supply systems.

The reducer maintains a constant predetermined outlet pressure (with the possibility of adjustment) in dynamic and static modes, regardless of changes in inlet pressure.

The gear case (1), cover (7), cap (10) and plug (11) are made of high-quality brass CW 617N (according to uropean standard EN 12165) by beating, forging and turning with nickel plating of external surfaces.A movable piston (2) is located in the housing, on the same axis with which a valve (13) is fixed. These parts and the adjusting sleeve (9) are made of the same brass by turning.

The spring (8) is made of AISI 304 stainless steel. Valve gaskets (14) and plugs (12), small (3) and large (4) o-rings are made of wear-resistant NBR rubber.
