WILLIAMS CONTROLS 130845 Part Description
Manufacturer
Features & Benefits
- Three-way valve configuration controls supply delivery and exhaust airflow within pneumatic circuits
- Pilot pressure activation range triggers diaphragm movement for consistent valve actuation response
- Integrated breather assembly limits contaminant entry and reduces internal moisture buildup
- Rapid exhaust function releases downstream air quickly during system disengagement cycles
Williams Controls Normally Closed Relay Valve
Ensure responsive braking control with the Williams Controls Normally Closed Relay Valve. Designed as a pilot-operated three-way non-compensating valve, it remains closed until pilot pressure between 35–45 psi actuates the internal diaphragm. This action unseats the poppet and directs supply air to the delivery port for controlled system response. When pilot pressure is removed, the valve closes and quickly exhausts downstream air to atmosphere, supporting rapid release. An integrated WM111B breather helps protect the control circuit from contamination, ensuring consistent operation with the Williams Controls 130845 WM147L1 normally closed relay valve.
