Pilot Regulating Horizontal and Vertical Trim for Model J Flow Control Valve. Engineered to maintain consistent discharge pressure and efficient water flow control, it’s particularly effective in systems with high-pressure water supplies, where managing excess flow is crucial. The system minimizes pressure surges and water hammer, protecting system components and ensuring smooth operation. A key benefit is the ability to perform remote shut-downs quickly, an essential function when post-operation aborts are required.
