Pressure Reducing Valve Manufacturer in Germany – Valvesonly Europe

Valvesonly Europe is a leading Pressure Reducing Valve Manufacturer in Germany, producing pilot-operated and direct-acting valves for stable downstream pressure regulation. Designed and tested in Germany under PED 2014/68/EU, our valves provide consistent outlet pressure regardless of inlet fluctuations. They are engineered for municipal water, fire protection, irrigation, and industrial utility applications including steam, gas, and seawater systems. Each valve undergoes full hydrostatic and seat-leak testing to ensure dependable performance and long service life.

Function & Working

A pressure reducing valve automatically maintains a pre-set downstream pressure by modulating its opening area through hydraulic pilot control. The pilot senses outlet pressure and adjusts the main diaphragm or piston position using the line’s own pressure energy. As downstream pressure rises above the setpoint, the pilot throttles the main valve; when pressure drops, it reopens. This self-contained system provides precise, vibration-free regulation without external actuators or power supply.
