This 2-way normally closed valve features 1/4" NPT connections and is engineered for precise refrigerant flow control in smaller tonnage systems

Natural Gas Optimized: Orifice and stabilizer design are tuned for the BTU content and flow characteristics of natural gas pilot applications

High BTU Rating: Handles up to 710

ensuring the system capacity remains balanced without the need for high-side pilot gas

20-Micron Filtration: Provides efficient particulate removal to protect sensitive system components like TXVs and capillary tubes

Velocity Boiler Works (Crown) 230125 Sensor 320788-702 This 2-way normally closed valveThe Velocity Boiler Works 230125 Sensor is a critical Return NTC Sensor (TSD00BD) designed for precise thermal monitoring within high efficiency hydronic systems. As a genuine OEM replacement for Crown and Velocity Boiler Works units, this negative temperature coefficient sensor provides the high accuracy resistance feedback necessary for the control board to modulate firing rates and maintain narrow temperature differentials.
