Hydrolevel EL1150 Sensing Probe 328140-751 The internal NPT thread connections

The internal NPT thread connections and maintenance-free design make it a reliable choice for contractors installing unit ventilators or VAV box reheat coils where accurate flow control is a non-negotiable requirement for system efficiency

The GC Valves S211GF02V5FG9 typically operates with a minimum pressure differential required for the diaphragm to lift

If the valve body is free of cracks and the seat is not scored

this component features a factory-set 200°F limit to protect the heat exchanger from thermal stress

this 2-wire actuator provides silent operation with a patented air brake system that prevents the slamming and gear noise common in standard spring-return units

Hydrolevel EL1150 Sensing Probe 328140-751 The internal NPT thread connectionsThe Hydrolevel EL1150 Sensing Probe (Part Number 45 210) is a critical component designed for 1150 Series Low Water Cut Off (LWCO) controls. Engineered for high temperature and high pressure residential or commercial boiler applications, this probe utilizes a 3 4" NPT threaded connection and features a precise 1 15 16" inside dimension (ID). This specific length is crucial for maintaining the 1 4" minimum clearance from the metal probe tip to the
