RC 28-200

RC 28-200

2-Way Relay

A 2-Way, hydraulically operated, diaphragm actuated relay valve, applicable for service on deluge and pre-action valve trims. The RC 28-200 is designed to meet the requirements of hydraulic valve control trims, particularly when a fast reaction is required. When the pressure command is removed, the pressure in the RC 28-200 relay drops, causing it to open and allowing the water to drain from the deluge valve’s control chamber.



  • Extremely large water passages enable fast response
  • Tough and durable construction
