Vent Limiting Devices

Vent Limiting Devices

Maxitrol vent limiting devices eliminate the need to run vent piping to the outside. They are designed for use indoors and in spaces where limiting the amount of gas escapement due to diaphragm failure is critical. Vent limiting devices should not be used outdoors if they are exposed to the environment. Ball check permits unobstructed inhalation for fast regulator diaphragm response on opening cycle, but limits gas escapement to be within ANSI and EN 88 require­ments should a diaphragm rupture.

KVOP‑4 325–7A, 325–7AL, 325–9L
Vent Screen

Vent Screen

Brass, 40 mesh screen flame arrestor for insertion in vent outlet. Prevents ignition of gas-air mixture which might be present in upper diaphragm chamber.

 

Model Thread
13A03‑1 For ⅛” NPT vent
13A03‑2 For ¼” NPT vent
13A03‑3 For ⅜” NPT vent

PF10 Pressure Tap Connector

Pressure Tap Connector

Pressure tap connector installed as part of the control. It is a hose fitting incor­po­rating a captured sealing means for testing inlet and outlet pressures. This elimi­nated the need for a special barb fitting.

 

Model Thread
PF10 ⅛” NPT
Dust Cap

Dust Cap

Used on vent opening to prevent blockage of the breather hole from dust of other foreign particles. Press-in plastic cap.

 

Model Thread
