MixCal 1/2 In Adjustable Thermostatic Mixing Valve (NPT), Series 521

Stable mixed temperature performance with durable construction for long life. Due to its unique mixing chamber design, MixCal produces a stable mixed water temperature, regardless of varying inlet temperatures and pressures. Scale formation is minimized by using sliding surfaces constructed of an anti-scale polymer, thereby guarding against seizing or erratic temperature fluctuations. Durable peroxide-cured EPDM O-ring seals resist wear from common water treatment additives such as chlorine and chloramines. Complies with standards
