Apollo model 58A balance valves are precision engineered and manufactured valves which provide two position hydronic circuit isolation capability and multi-turn throttling adjustment as required for proportional balancing of hydronic systems. the unique integrated digital readout in the handle allows qualified technicians to easily adjust the valve to achieve a highly accurate flow. valve pressure drop can be read through the valves integrated 1/4” measurement ports, and flow calculated from the flow coefficient associated with the numerical setting.the integrated fixed orifice offers greater accuracy than that of a variable orifice.

 • compatible with all flow meters easy adjustment and setpoint indicator
 • CWP: 300 psi (200 CWP for push fittings)
 • temperature range:15°F to 300°F (-10°C to 150°C)
