This NSF\/ANSI 61 and 372 certified valve is rated for a maximum working pressure of 200 psi and a maximum operating temperature of 180°F (82°C), making it ideal for demanding commercial, industrial, and agricultural water systems.\u003c\/p\u003e\n\u003cp\u003eThe Flo-Trol® CDH series uses a \u003cstrong\u003eflexible Buna-N flow-control orifice\u003c\/strong\u003e with no moving internal mechanical parts. As system pressure changes, the elastomeric orifice flexes to maintain a nearly constant flow rate within ±15% between 15 and 125 psi. The all-stainless-steel body construction provides excellent corrosion resistance and long service life in harsh environments.\u003c\/p\u003e\n\u003cp\u003eCDH series – All stainless-steel body with NSF 61 approved Buna-N flow-control orifice.
