VALVES
Valves - One-Stop Supply for Your Piping Package
Ball, gate, globe, check, butterfly and diaphragm valves integrated with your pipes, fittings and flanges - one order, one shipment, unified EN 10204 3.1 documentation.
BALL VALVES
Ball Valves
Floating and trunnion-mounted balls; one-piece, two-piece and three-piece bodies; flanged, threaded, butt-weld and grooved ends.
Floating Ball Valves
1-pc / 2-pc / 3-pc bodies for general shut-off of water, oil, gas and steam lines; full-bore and reduced-bore options.
Trunnion & High-Pressure
Trunnion-mounted and forged-steel high-pressure designs; metal-sealed high-temperature service up to about 950 degrees C.
Cryogenic & Sanitary
Extended-bonnet cryogenic valves for LNG and LO2/LN2 at -196 degrees C; clamp-end sanitary valves with EPDM or PTFE seals.
GATE GLOBE CHECK
Gate, Globe and Check Valves
Wedge gate with OS&Y bolted bonnet, globe and piston types, swing / dual-plate / piston check; cast and forged bodies.
Gate Valves
Wedge gate valves (OS&Y, bolted bonnet) for full-bore isolation in waterworks, pipelines and utility service.
Globe Valves
Globe and piston valves for accurate throttling and frequent on-off regulation of steam, water and process fluids.
Check Valves
Swing, dual-plate and piston check valves that prevent reverse flow and protect pumps from backflow damage.
BUTTERFLY & SPECIAL
Butterfly and Special Valves
Wafer, lug and flanged butterfly valves; sanitary diaphragm; knife gates; strainers.
Butterfly Valves
Wafer / lug / flanged, centerline and double-eccentric, EPDM, PTFE or metal seats - the cost-effective choice for large-diameter water and HVAC lines.
Diaphragm & Knife Gate
Sanitary diaphragm valves for water treatment, chemical dosing and hygienic lines; knife gate valves for slurries, sludge and powder.
Strainers & Actuation
Y-type and basket strainers protecting valves, pumps and meters; pneumatic and electric actuators to ISO 5211.

Manual lever and gear; pneumatic and electric actuators with ISO 5211 mounting pads.
WHY WITH YOUR FITTINGS
Why Buy Valves with Your Fittings
The interface risk disappears when one vendor coordinates valve, pipe and flange.
01
End-to-End Compatibility
Flange drilling, weld-end schedules and face-to-face dimensions are coordinated with the fittings and pipes in the same package - no interface disputes on site.
02
One Documentation Set
One purchase order, one shipment, unified EN 10204 3.1 documentation - ideal for EPC projects, skid builders and MRO buyers.
03
Fewer Vendors
Valves arrive with matching gaskets, bolts and the pipe schedule you ordered - fewer deliveries to track and fewer mismatches to resolve.
