two-pipe thermostats regulate their own supply air and do not require an external inline restrictor

The weights are rated for temperatures up to 150°F (66°C)

Whether managing industrial water control

Technicians favor this model for its pilot-operated diaphragm design

Resideo 45900446-052/B Venturi 323055-751 two-pipe thermostats regulate their ownProperly calibrate your gas control systems with the Resideo 45900446 052 B Venturi, a precision engineered manifold component designed to interface specifically with Honeywell VK41 and VK81 series gas valves. Built from high grade thermoplastic to withstand the rigors of industrial ventilation and gas distribution, this replacement venturi maintains consistent fluid dynamics and pressure differentials critical for high efficiency combustion.
