Magnum 20 features integral Eccentric-Seal™ butterfly shutoff valves for a short lay length, and Dual-Action™ checks for high performance at low-and high-flow rates. It may be installed under continuous pressure service to protect against both backpressure and backsiphonage. Maximum working pressure is 175psi (12 bar).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntegral shutoffs for shorter lay length and lightweight construction\u003c\/li\u003e\n\u003cli\u003eDual-action check modules for low-and high-flow performance\u003c\/li\u003e\n\u003cli\u003eStainless Steel Body and Shutoffs\u003c\/li\u003e\n\u003cli\u003eTamper-resistant test cocks\u003c\/li\u003e\n\u003cli\u003eIncludes: Test Cocks\u003c\/li\u003e\n\u003cli\u003eIncludes: Tamper Switch\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 hazard level is this Double Check approved for?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt is rated for low health hazard (non-toxic, \"pollutant\") cross-connections only.
