• Lightweight, wafer type check valve with face-to-face dimensions according ISO 5752, table 5 long
• High flow capacity featuring a special shaped disc with a large opening angle resulting in high Kv values
• Spring loaded disc for positive shut-off
• Choice of cast iron or stainless steel body types
• Field replaceable O-ring seat
• Internal travel stop prevents the disc from slamming against the pipe
• Excellent low pressure shut-off The standard low pressure shut-off is less than 0.1 bar (10 kPa)
• Replaceable, metal-reinforced seat, completely encapsulated by rubber, isolates
the stem and body from the media and eliminates seat distortion due to high vac-
uum or turbulence.
• Primary stem seal, formed by preloaded contact of disc hub with flatted seat sur- faces, completely isolates stem and body from the line media.
• Secondary stem seal, formed by an engineered interference fit of the stem through the seat, provides additional sealing integrity.
• Rounded, polished disc edge provides full 360 degree concentric seating, minimum flow restriction, lower seating and unseating torques and maximum seat life.
• Uninterrupted gasket surfaces help eliminate problems associated with seat retaining screws in the gasket surface and allows use of standard spiral wound gaskets.
• Valve stem designed to API 609 standards is blow-out resistant.
• Seat retaining ring is housed within the flange gasket ID to eliminate potential emission path.
• Face-to-face conforms to MSS SP-68 and can be configured to ISO 5752 short.
• Adjustable packing utilizes unique rocker-shaped gland bridge that compensates for uneven adjustment of gland nuts.
• Extended neck allows for two inches of clearance for insulation.
• Suits all linear actuated valves.
• Engineered to provide the maximum force output with minimum supply pressure.
• Simplicity and reliability are the fundamental design parameters.
• Rugged yet functional design.
• Operates with or without lubrication.
• Simple to retro-fit.
• Wide range of sizes available.
• Maintenance friendly.
• Ideal valve for dense slurry and solids applications and wet or dry abrasives.
• Slide through gate design cuts through solids providing consistent operation in the most difficult applications.
• O-port style gate fully protects the seat face in open position, giving you longer service life.
• Will close through a static column of material.
• Fully fabricated from heavy plate and sheet.
• Available in 304, 316 and 317L stainless steel wetted parts or custom designed for your needs using a wide variety of materials including
• MSS face-to-face standard.
• Other special face-to-face dimensions are available.
• Precision machined seat with multiple gate guides.
• Uni-directional shut-off.
• Full operation, leakage and cycling tests.
• Certified test reports on request.
• Positive sealing which is mechanically achieved and does not rely on line pressure assistance.
• Bi-directional shut-off performance.
• Body design options: wafer, lugged or double flanged.
• Suitable for use on end-of-line service (lugged and double flanged).
• Available in 3 design options. Soft seated, fire-safe or metal seated.
