Bell & Gossett B138-1 #8 Brass Dual Unit Valve 1/2" NPT 30 PSI Relief 12 PSI Reducing

Reducing valves fill the system to a preset pressure for optimum performance. Combination dual unit valves include pressure reducing valve and relief valve. Both Valves are equipped with an EPDM diaphragm. The diaphragm operated relief valve operates with a low differential between opening and closing pressures. The diaphragm operated pressure reducing valve is equipped with an inlet strainer and built-in low inlet pressure check valve.

• Low inlet pressure check valve help prevent loss of system pressure if the supply water drops below system pressure
• Convenient cleanable strainer is designed to prevent dirt and sediment from entering the system
• Relief and B-38 pressure reducing component valves

Bell & Gossett EAS-1 Cast Iron Enhanced Air Separator, 1 Inch NPT, 35 gpm Bell & Gossett EAS-1 Enhanced Air Separator is a highly efficient device for removing entrained air bubbles in hydronic systems. The combination diffuser and coalescing medium design makes possible the removal of very small air bubbles from the fluid stream by coalescence at substantial fluid velocity. The diffuser forces the system fluid to cover the entire inlet portion of the coalescing medium. The coalescing medium will collect air bubbles on its stainless steel filaments. As the bubbles coalesce together, they will rise to the top of the separator where they can be released to the atmosphere through the automatic air vent.

Bell & Gossett Airtol ATF-12 Cast Iron Tank Fitting, 1/2", FNPT x FNPT Airtrol tank fittings help establish the proper initial liquid level in the compression tank when filling the hydronic system. They help maintain proper system pressurization by directing released air to the compression tank during system operation and permit cooler liquid flow to the boiler during the off cycle as system liquid cools. Airtrol tank fittings must be used with the appropriately sized in-line airtrol or rolairtrol air separator.
