Performance and characteristics:

Product Overview

The 200X Pressure Reducing Valve is a pilot-operated, diaphragm-actuated valve designed to automatically reduce higher inlet pressure to a stable lower outlet pressure in water systems. It maintains constant downstream pressure regardless of flow rate variations or upstream pressure fluctuations.

Key Features

Precise Pressure Control– Maintains outlet pressure within ±5% of set point
Self-Contained Operation– Requires no external power source
Wide Pressure Range– Handles inlet pressures up to 2.5MPa
Low Noise Design– Optimized flow path minimizes turbulence
Corrosion Resistant– Stainless steel trim and epoxy-coated body
Easy Maintenance– Top-access design for simple servicing

Working Principle

The 200X valve uses a pilot-operated diaphragm system to control pressure. When outlet pressure drops below the set point, the pilot valve closes, increasing pressure above the diaphragm which opens the main valve. When outlet pressure rises above the set point, the pilot valve opens, relieving pressure above the diaphragm and allowing the main valve to close. This automatic balancing maintains constant downstream pressure.
