Product Overview

Our 500X pressure relief valve provides precise and reliable overpressure protection for water supply systems, specifically designed to prevent pipe bursts and equipment damage. The pilot-operated design ensures accurate pressure control with zero leakage during normal operation.

Key Features

Precise Pressure Control – ±2% set pressure accuracy
Zero Leakage – Tight shutoff below set pressure
High Capacity – 30% greater flow than conventional valves
Corrosion-Resistant – 316 stainless steel trim standard
Easy Maintenance – In-line serviceable design

Working Principle

  1. Normal Operation: Main valve remains tightly closed

  2. Overpressure: Pilot system detects excess pressure

  3. Relief Phase: Main valve opens proportionally to overpressure

  4. Resetting: Automatically recloses when pressure normalizes

Applications

✔ Water Treatment Plants – Filter protection
✔ Pump Stations – Discharge line safety
✔ HVAC Systems – Chiller/boiler protection
✔ Fire Protection – Sprinkler system safeguards
✔ Industrial Water – Cooling system overpressure control

Medium
