Kromschroder 88012195 120V 1-1/2″ NPT Normally Open Vent Valve

Description

The Kromschroder 88012195 is a 120V, 1-1/2″ NPT normally open (N/O) vent valve engineered for use in double-block-and-bleed (DBB) gas safety shutoff systems. In commercial and industrial burner applications, this vent valve plays a critical safety role: when the upstream and downstream safety shutoff valves are de-energized and closed, the normally open vent valve opens automatically to bleed any trapped gas from the interblock cavity to a safe vent point — confirming gas-tight isolation and preventing dangerous gas accumulation.

Kromschroder, a trusted name in combustion controls and gas safety components, manufactures this valve to meet the rigorous demands of commercial boilers, industrial burners, and process heating equipment. The 1-1/2″ NPT connection ensures compatibility with standard gas piping configurations, while the 120V coil voltage suits North American electrical systems.

Key Features

• Normally open (N/O) operation — vents interblock cavity to atmosphere when de-energized
• 120V coil voltage for compatibility with standard North American control circuits
• 1-1/2″ NPT threaded connection for straightforward installation in existing gas piping
• Designed for double-block-and-bleed (DBB) gas safety valve trains
• Manufactured by Kromschroder — a leading authority in combustion safety and gas control
• Suitable for commercial and industrial burner, boiler, and process heating applications

Specifications

Application

This vent valve is intended for installation between two safety shutoff valves in a DBB gas valve train on commercial and industrial burner systems. When the system is shut down or de-energized, the N/O vent valve opens to release any residual gas pressure trapped between the two shutoff valves, providing a positive indication of valve seat integrity and preventing undetected gas leakage into the combustion chamber.
