Description
Waterous Piston Relief Valve
The Waterous Piston Relief Valve provides dependable pressure control for fire pumps, ensuring safe and efficient operation. This pilot-operated valve uses a small pilot valve to control the main valve’s function, offering enhanced sensitivity to pressure changes and a broader range of pressure control. Its design protects critical components in fire pump systems and other hydraulic applications from damage caused by excessive pressure.
How Does the Piston Relief Valve Work?
The Waterous Piston Relief Valve consists of two primary components: the pilot valve and the main valve. The pilot valve, located upstream, uses a spring and a pressure-setting screw to regulate fluid flow to the main valve. The main valve, located downstream, includes a piston and a spring.
When the pilot valve allows fluid to flow to the main valve, it exerts pressure on the piston. If the pressure exceeds the spring force, the piston moves, opening the main valve. Once open, the valve directs excess fluid from the system to the tank, reducing pressure and protecting components from potential damage.
Applications of the Relief Valve
Waterous Piston Relief Valves are widely used in fire pump systems to safeguard pumps and hoses during high-pressure operations. They also provide reliable protection for other hydraulic systems, such as mobile hydraulic excavators and cranes, ensuring consistent performance under demanding conditions.
