SR Series - Howell Pipe

1 SR Series Butterfly Valves CRN: Butterfly Valves Quality is designed into every Stonetown Stonetown Butterfly Valves meet the Butterfly Valve. The SR Series features rigorous requirements of industrial applications precision machined parts and utilizes a requiring positive shut off/zero leakage in the phenolic backed cartridge seat to ensure handling of liquids, gases, and slurries. years of dependable operation. Industries include: HVAC, Food and Beverage, OEM, Chemical/Petrochemical, Pulp and Paper, Water Purification, EPOXY CORED BODY.

2 Stonetown Butterfly Valves are available and Power & Utilities. 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 DISC and SHAFT CONNECTION. complies with API 609, ISO5752, and MS-SP67. The disc and shaft double D connection features all the benefits of a high strength 2-piece design without the MOUNTING FLANGE disadvantages associated with designs that utilize Universally recognized ISO 5211 standard taper pins or disc screws which often fail for adaptation to pneumatic and electric prematurely through abrasion, corrosion, or actuators, mechanical position fatigue.

3 Transmitters, gear operators and handles. DEAD END SERVICE. Lug body valves are recommended for BUSHINGS (2) applications where downstream piping must be Teflon stem removed. Placement of a bushings downstream flange is reduce recommended to operating comply with torque as well suggested safety as provide practices. Lug style maximum shaft butterfly valves are support and rated for 150 PSI in dead alignment while isolating end service. the stem from the valve body, preventing TESTING. corrosion in the Stonetown butterfly stem journal valves conform to API.

4 And ultimately 598 and BS5155. All stem seizure. valves are subjected to a body pressure test of 150% and DISC shell 110% of All Stonetown working pressure. disc castings are spherically machined &. polished for extended seat life and zero MOULDED O-RING eliminates the leakage/bubble tight shut off. need for flange gaskets SEAT. The completely encapsulated phenolic BUSHING. 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.
