It features a brass body. Rated to 225 psi and up to 250°F.\u003c\/p\u003e\u003cp\u003eThe VR10XL Vacuum Relief Valve is utilized to protect both commercial and residential water supply systems and pressure vessels from internal vacuum conditions draining a system by siphonage, collapsing storage tanks, and damaging heating elements. Its low-lead brass valve body and 300 series stainless steel internals protect against corrosion, while its silicone elastomers provide a durable, reliable seal. Features of the VR10XL include a maximum working water pressure of 200 psi, a maximum working water temperature of 250°F, and a capacity of 13 CFM. It is available in two convenient sizes for easy installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWater tank collapse prevention reduces maintenance and replacement costs\u003c\/li\u003e\n\u003cli\u003eSafely protects against internal vacuum conditions\u003c\/li\u003e\n\u003cli\u003eStainless steel internals resist corrosion\u003c\/li\u003e\n\u003cli\u003eCSA Compliance to ANSI Z21.22\/CSA 4.4\u003c\/li\u003e\n\u003cli\u003eCertified to NSF\/ANSI 372 by IAPMO R\u0026amp;T\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat pressure does this relieve at?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eNone - this is a vacuum relief valve, not a pressure relief valve.
