Satterlund Supply carries a precision-engineered selection of brass air cocks—also known as air release or petcock valves—designed for effortless venting and bleed-off in pneumatic, hydraulic, and steam systems. Our brass air cocks feature durable, leak-proof ball or cone valves with PTFE or Buna-N seals, offering rapid air evacuation and reliable drip-tight shutoff under fluctuating pressures. Manufactured to meet ASTM B16.15 and MSS SP-110 standards, these brass air release fittings ensure long-term corrosion resistance and smooth operation in compressors, boilers, and process lines.

Satterlund Supply offers a full line of backflow preventers and vacuum breakers—designed to protect potable water systems from contamination and ensure code compliance in commercial, industrial, and residential installations. Our backflow preventers—including dual-check, reduced-pressure zone (RPZ), and double-check valves—provide reliable back-pressure and back-siphonage protection, while our atmospheric and pressure-type vacuum breakers safeguard against negative-pressure events. Manufactured to ASSE, AWWA, and CSA B64 standards from durable bronze, brass, and stainless steel, these devices deliver leak-proof performance and long service life.

Satterlund Supply offers a comprehensive range of balancing valves and circuit setters—designed to optimize flow and ensure hydraulic balance in HVAC, hydronic heating, and chilled-water systems. Our precision-engineered balancing valves deliver accurate differential pressure measurement and fine-tuning of flow rates, while our circuit setters provide factory-calibrated, tamper-proof flow control for individual heating or cooling circuits. Manufactured to meet ANSI/ASME and EN standards, these valves feature rugged bronze, brass, or stainless steel bodies and integrated pressure gauges or test points for easy commissioning and maintenance.

Satterlund Supply offers an extensive selection of high-performance mixing valves—featuring thermostatic mixing valves, proportional (modulating) mixing valves, and multi-port diverter valves—for precise temperature control in plumbing, hydronic heating, and HVAC systems. Our thermostatic mixing valves maintain stable outlet temperatures to protect against scalding and thermal shock, while our proportional valves deliver smooth, automated blending of hot and cold fluids for radiators, radiant floors, and solar thermal loops. Manufactured to ASSE 1017, CSA B125, and ANSI/ASHRAE standards from durable bronze, brass, or stainless steel, these mixing valves ensure reliable operation and long service life.
