Reliance Valves Pressure Reducing Valves (PRVs) prevent damage to heating systems, appliances and buildings by reducing high inlet pressures from the mains water supply to a safer lower outlet pressure.

Pressure reducing valveadjustment

Our extensive range of Pressure Reducing Valves effectively control pressure and flow rates across domestic, commercial and industrial buildings. From compact solutions for tight spaces, to larger high-performance designs and single-piece cartridges for easier serving and maintenance, we offer you a range of options to suit your specific pressure reducing valve application and installation requirements.

Most Taco Expansion Tanks are available with either bladders or diaphragms so that water and air are permanently separated. No absorption can take place at any point during the system cycle, and you avoid the problems of waterlogged tanks, air-bound terminal units, excessive corrosion, inefficient balancing and pump cavitations. Plain steel tanks are also available. Please see information and links below.

Taco Expansion Tanks are used in the following applications, pressure stabilization in water based mechanical systems such as booster installations, boiler systems, and chiller plants.
