Quality is designed into every Stonetown Butterfly Valve. The SR series features precision machined parts and utilizes a phenolic backed cartridge seat to ensure years of dependable operation.

Stonetown Butterfly Valves meet the rigorous requirements of industrial applications requiring positive shut off/zero leakage in the handling of liquids, gases, and slurries. Industries include: HVAC, Food and Beverage, OEM, Chemical/Petrochemical, Pulp and Paper, Water Purification, and Power & Utilities.

EPOXY CORED BODY Stonetown Butterfly Valves are available in sizes 2”– 24”, tapped lug body, or wafer design with locating holes. Both designs are for use with ANSI 125/150 weld-neck or slip-on flanges. Basic design complies with API 609, ISO5752, and MS-SP67.

MOUNTING FLANGE Universally recognized ISO 5211 standard for adaptation to pneumatic and electric actuators, mechanical position transmitters, gear operators and handles.

DISC and SHAFT CONNECTION The disc and shaft double “D” connection features all the benefits of a high strength 2-piece design without the disadvantages associated with designs that utilize taper pins or disc screws which often fail prematurely through abrasion, corrosion, or fatigue.

BUSHINGS (2) Teflon stem bushings reduce operating torque as well as provide maximum shaft support and alignment while isolating the stem from the valve body, preventing corrosion in the stem journal and ultimately stem seizure.

DEAD END SERVICE Lug body valves are recommended for applications where downstream piping must be removed. Placement of a downstream flange is recommended to comply with suggested safety practices. Lug style butterfly valves are rated for 150 PSI in dead end service.

DISC All Stonetown disc castings are spherically machined & polished for extended seat life and zero leakage/bubble tight shut off

TESTING Stonetown butterfly valves conform to API 598 and BS5155. All valves are subjected to a body pressure test of 150% and shell 110% of working pressure.

MOULDED O-RING eliminates the need for flange gaskets

SEAT The completely encapsulated phenolic backed elastomer offers advanced performance while maintaining low torque. The seat incorporates primary seals that mate with the hub portion of the disc. The upper and lower shaft journals incorporate a moulded double O-ring secondary seal.
