CLARKSON URETHANE KNIFE GATE VALVES FIGURE SU10R The SU10R valve offers bi-directional isolation with a field replaceable snap-in liner that completely protects the wetted area from abrasion and corrosive slurries, increasing reliability and service life GENERAL APPLICATION TECHNICAL DATA The Clarkson SU10R valve is designed for a wide range of isolation applications in low to medium density slurry applications such as: • Mining and mineral processing • Coal preparation plants • Chemical plants • Corrosive environments • Wastewater treatment plants Size range: DN 50 - 600 NPS 2 - 24 Temperature rating: 50°C (120°F) on liquid service 80°C (175°F) on dry service Pressure rating: 1000 kPa (150 psi) at cold working pressure (non-shock) Not suitable for vacuum service NOTE Patent pending * To ensure effective integral flange seal, pipeline flange internal diameter should not exceed ASME B16.5 minimum slip-on/socket welding bore dimension. Slip-on flanges are suitable within this limitation. • True bi-directional flow and shut-off, allowing it to be installed in either direction. • Unique one-piece precision molded high strength polyurethane liner protects the wetted parts from corrosion and abrasion. • Liner is field replaceable in all sizes, no need to return to factory for repair. • Liner has integral flange seals eliminating the need for flange gaskets in most cases*. • Liner employs sealing beads to support and wipe slurry from the gate during operation, minimizing deflection and improving packing life. • It can replace conventional and short pattern slurry knife gate valves. As a true pressure vessel valve the SU10R does not discharge to atmosphere when cycled. • Compact two piece split body construction for ease of maintenance. • Testing as per MSS SP-151. • Pressure rated 316 stainless steel gate, with optional 17-4 ph to provide improved abrasion resistance against the rigors of abrasive applications. • Full round port and seat design offers low pressure drop across valve and longer service life in abrasive applications. • Designed to be a repairable asset, lower the cost of ownership. • Inverted self-aligning gland box allows for easier setup and longer packing life. • Complies with MSS SP-81 face-to-face dimensions. • All valves are factory pressure tested. • A range of actuation options from manual hand wheel, bevel gear, chain wheel to pneumatic, hydraulic, and electric actuators. Consult Sales for advice on using SU10R in applications with non-metal pipe/liner/flange.
