NV Namur Air Lock & Bypass Valve

NV42L Air Lock

NV42L Air Lock is a 4 way (2 in, 2 out) 2 position Lever-Operated valve for double acting and spring return actuators. When the plunger is depressed, air passes freely from the supply line to the pneumatic actuator. When the plunger is extended, the air is locked inside the pneumatic actuator. Typical application is to lock valve in position in case of line maintenance or in case of solenoid test or repair without moving the actuator.
NV42L Air Lock is designed to be wafer mounted between a NAMUR solenoid valve and NAMUR actuator eliminating costly tubing and fittings (available NP1/4 threaded adapter can be installed directly on air inlets in order to obtain 1/4" NPT threaded inlet ports). An inductive sensor to detect valve engaged can be provided (NV42L-24R). This option is used to give control room signal of valve locked.

NV62L Bypass

NV62L Bypass is a 6 way 2 position Lever-Operated valve for double acting and spring return actuators. When the plunger is depressed, air passes freely from the supply line to the pneumatic actuator. When the plunger is extended, the supply air is locked out from the pneumatic actuator at the same time NV62L vents the internal pressure from the actuator to the atmosphere. Typical application is in combination with declutchable gear overrides in order to exhaust air from actuator before manually operating the valve.
