The CSA direct acting pressure reducing valve stands out for its innovative design and high reliability. Designed to satisfy the strictest quality standards the valve’s operating principle revolves around a pressure balanced piston with self-cleaning technology to reduced maintenance ensuring high and long lasting performances. The CSA pressure reducing valves are spring loaded without any circuitry, diaphragm, filters and pilots in need of maintenance, frequent inspections. The compensation chamber of the spring loaded direct acting pressure reducing stabilizing valve is designed to work water tight also in static condition maintaining the required downstream pressure set point regardless of upstream pressure variations. A wide range of springs are available for different adjustments of the outlet pressure. The large expansion chamber makes the CSA VRCD suitable to tolerate high differential pressure conditions, without the risk of damage cavitation. The piston allows for a PN 40 bar rating and for a greater safety and reliability compared to diaphragm actuated valves. The maintenance can be easily performed from the top without the need of removing the valve from the pipe. Several material of o-rings and selections of elastomers are available for the proper use in water distribution networks, cooling systems, industrial sites and buildings. The direct acting piston technology ensures for the proper working also with air and in vertical position, extremely useful in confined spaces chambers and civil installation plants. Another very important aspect is the reaction time of the spring loaded pressure reducer VRCD as a consequence of a possible sudden increase of the downstream pressure. Should that happen diaphragm actuated control valves do not keep up as the hydraulic inertia will make them unable to perform, instead the CSA direct acting pressure reducing valve will always maintain the downstream pressure required set point, regardless of upstream pressure variations, changes in demand.
