Amerex Vent Check 10173 - OEM

The Amerex 10173 Vent Check (Vent Plug) is a safety valve designed for use in actuation networks that rely on nitrogen pressure (such as modular dry‑chemical or ICS systems). Installed downstream of the pneumatic control head, it relieves built-up residual pressure after system discharge, preventing accidental or delayed reactivation. Constructed from machined brass with an internal spring and nylon ball, it ensures reliable operation and helps maintain system integrity.

Key Features:

• Built of durable, machined brass for long-term reliability. 

• Internal spring and nylon ball mechanism to safely vent pressure.

• ¼″ female NPT connection for integration with pneumatic controlheads. 

• Plastic dust cap included to protect the valve when not in service. 

• Required in systems using nitrogen actuation, such as Modular Dry Chemical or ICS. 

• Easily accessible location recommended for post‑discharge pressure bleeding.
