Improved with a stainless-steel relief valve seat, this rugged assembly yields greater dependability and extended valve life. Fitted with OSY shutoff valves. Maximum working pressure: 175 psi (12.1 bar).

This series features an integrated flood sensor with SentryPlus Alert® Technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.

MasterSeries LF886V-FS Lead Free* reduced pressure zone detector assembly backflow preventers help protect against high hazard (toxic) fluids in water services to industrial installations and applications. The Lead Free* construction complies with low lead installation requirements.

The ductile iron body is fused with ArmorTek™ coating technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate.

Primary Industry Classification:Fabricated Metal Product Manufacturing Established:1956 Beginning in New York City as a small specialty manufacturer servicing the valve industry, Mueller Steam Specialty incorporated in 1956 to start manufacturing pipeline strainers. Since then, the company and its product offering have expanded dramatically. The company moved to North Carolina in 1972 and due to its continued growth, moved again in 1992 to a new and larger facility in St. Pauls, North Carolina. There are now over 300,000 square feet of ISO 9001:2008 registered manufacturing space devoted to Mueller’s various product lines. In addition to a full range of pipeline and specialty strainers, the company now manufactures a broad offering of check valves and butterfly valves. Mueller Joins the Watts Family In December 2005, Mueller became a part of the Watts Water Technologies, Inc. family of companies.
