The Watson McDaniel HB1010R-17N-PA100 is a 2-way stainless steel pneumatic control valve from the HB Series, designed for precise modulation of steam, water, or air in industrial process systems.
It features a reduced-port valve body (R-series) with a contoured stainless steel plug that provides accurate flow control and stable performance across varying load conditions. The valve is operated by a pneumatic actuator (3–15 PSIG control signal), allowing it to modulate flow in response to an external control system such as a PID controller or building automation system.
Built with a rugged stainless steel body and Teflon stem packing, the HB Series is engineered for durability in high-temperature and high-pressure environments, including steam service. The valve is commonly used in HVAC, process heating, and industrial fluid control applications where reliable throttling control is required.
The “17N” designation indicates a 2″ NPT connection size, making it suitable for medium-capacity piping systems. The PA100 actuator configuration typically corresponds to an air-to-open (normally closed) fail-safe operation, commonly used in heating applications for safety and control stability.
