REMOTE RESET VALVES FOR CRITICAL APPLICATIONS
RAK- Remote Reset Latching Valve
VERSA’s RAK Series Remote Reset Latching Valves are engineered for safety-critical and remote applications where fail-safe operation and manual reset are essential. With rugged stainless-steel construction and positive latching mechanisms, the RAK Series ensures reliable valve actuation in emergency shutdown, fire safety, and remote isolation systems.
Key Features
The VERSA RAK Remote Reset Latching Valve is designed to enhance safety, reliability, and operational efficiency in critical process applications. Its innovative dual-solenoid design allows testing, reset, and control functions without interrupting operations—improving both plant performance and safety compliance.
Remote latch reset
Enables partial valve stroke testing (PVST) and remote reset of spurious trips without manual intervention, improving safety and uptime.
Dual-solenoid operation
Integrates an ESD solenoid with an air latch manual reset and a remote reset solenoid for flexible local and remote control.
Enhanced testing capability
Allows independent cycling and testing of solenoids without process disruption, reducing the probability of failure on demand.
Durable stainless steel construction
Built from 316 stainless steel for superior corrosion resistance and long service life in harsh environments.
Safety performance
Rated for Safety Integrity Level (SIL 3) under specified conditions, ensuring compliance with safety instrumented system requirements.
