Valfonta's PRV30 pressure reducing valve is a direct-acting, self-regulating, piston-balanced valve. It is designed to provide a constant and accurate outlet pressure, effectively absorbing any oscillations that may occur in the inlet pressure..
This model stands out for being manufactured entirely in Stainless Steel AISI 316L (body, cap and interiors), which makes it the ideal solution for demanding applications such as chemical laboratories, sanitary plants, water distribution systems and compressed air. chemical laboratories, sanitary plants, water and compressed air distribution systems.. Its compact and robust design allows it to be installed in any position. any position. because its internal configuration ensures effective fluid circulation regardless of orientation. . In addition, it is a valve that maintenance free.

Compatible fluids: Suitable for liquids and gases of group 2 (compressed air, water, neutral gases, etc.).
The PRV30 operates by means of a direct acting system. The fluid enters the valve and the inlet pressure tends to close it due to the section difference. Regulation is achieved by force balance:
-
Opening: By compressing the regulating spring by means of the upper screw, force is exerted on the piston to open the valve and allow the fluid to flow through.
-
Regulation and closing: The downstream pressure acts on the piston in the opposite direction to the spring. When the downstream pressure reaches the set value, the valve is balanced. If the downstream pressure exceeds the set value, the valve closes tightly. closes tightly.
-
Stability: Even when consumption is zero (downstream valves closed), the PRV30 absorbs oscillations and maintains stable static pressure..
To ensure optimum performance and warranty validity, follow these guidelines:
-
Mounting Position: Although installation in horizontal piping is recommended horizontal pipingits design allows mounting in any position any position (vertical or inverted) without affecting the operation of the system..
-
Filtration: It is highly recommended to install a strainer filter upstream to protect the piston and seal from impurities that could damage the seal..
-
Safety Valve: It is advisable to install a relief or safety valve at a distance of between. 0.5 to 1 meter from the outlet of the reducer to assure a correct compensation.
-
Adjustment: Adjustment is made with an 8 mm Allen wrench. Turn the screw clockwise clockwise (compressing the spring) to increase the output pressure and counterclockwise to decrease the output pressure..
