ASCO S262SH02N3JK4 2 Inch No 120V 0/15# Vent Valve

The ASCO S262SH02N3JK4 is a 2-inch normally open vent valve used to control gas flow in a variety of industrial applications, most notably HVAC systems. When not in use, this electro-pneumatic valve, which runs on a conventional 120-volt AC power source, allows gas to flow freely. When engaged, the valve closes, preventing the flow of gas.The ASCO S262SH02N3JK4 valve's generally open position provides various benefits to HVAC systems. In its unpowered state, the valve provides constant ventilation, minimizing pressure buildup and ensuring optimal system performance. This is critical for operations such as purging air from lines and ensuring correct venting during equipment operation. Furthermore, the electro-pneumatic architecture allows for quick and dependable control of gas flow, making it ideal for applications that require precision control or rapid shutoff.
