VSP-18 Edco Vacuum Switch Protector

Sku#: VSP-18

Contact us for availability.
The Edco VSP-18 vacuum switch protector uses G 1/8 NPSF threads. The Edco VSP18 vacuum switch protector is bi-directional and acts as a pressure relief valve that vents excess pressure to atmosphere via a dilating o-ring check valve.

The primary cause of vacuum switch failure is accidental over-pressure from air-assisted blow-off circuits. Edco's vacuum switch protector is bi-directional and acts as a pressure relief valve that vents excess pressure to atmosphere via a dilating o-ring check valve. An internal tortuous flow path snubs pressure spikes but allows full vacuum pressure to be monitored by the switch that is being protected.
