Boiler Blowdown Back-Pressure Control
Without enough back pressure, hot boiler water can flash to steam in the blowdown line, reducing control accuracy and causing wear. The 12-046-01 holds back pressure in the line so that blowdown rates stay consistent.
Indexed Position Indicator
The indexed indicator makes it easier to record, repeat and fine-tune valve settings during commissioning and routine conductivity control adjustments.
Bronze and Stainless Steel Construction
A bronze body paired with a stainless steel disc and seat supports high-temperature boiler service up to the published 300 psi at 550 F rating.
Orifice Plates
Distributor listings indicate an orifice union with plates of 1/16, 1/8, 1/4 and 5/16-inch for blowdown flow sizing. Confirm included components with the current Pulsafeeder valve packages datasheet.
Typical Applications
Used with Pulsafeeder boiler controllers and motorized blowdown valves for automatic conductivity-based surface blowdown on steam boilers.
Installation and Safety
Isolate and depressurize the blowdown line and allow it to cool before installation or adjustment.
