100% Bubble-Tight Sealing: Achieve zero leakage (ISO 5208 Rate A) even under low pressure, saving water and reducing pump load.
Durable EPDM Coating: Fully vulcanized rubber lining on the gate provides excellent corrosion resistance and a long service life (20+ years).
Full Bore & Flat Bottom: No sediment accumulation, ideal for raw water and sewage applications with debris.
Superior Corrosion Protection: Fusion-bonded epoxy coating inside & out (WRAS/ACS approved) prevents red water.
Low Torque Operation: O-ring stem seals reduce friction, allowing easy manual operation even for large diameters (DN300+).
OEM & Customization Ready: We support custom flanges (ANSI/BS/JIS), coatings, and gearboxes.

Wafer Type: Ultra-compact design installs between two flanges — saves space and weight.
Single Plate (Swing Disc) or Dual Plate (Twin Disc): Options for different flow conditions.
Low Pressure Drop: Streamlined disc design minimizes flow resistance.
Fast Closing: Springs assist rapid disc closure to prevent water hammer.
Silent Operation: No slamming noise compared to traditional swing check valves.
Vertical or Horizontal Installation: Flexible mounting orientation.

Wafer/Insertion Type: No flanges — installs between pipe flanges using through-bolts.
Ultra-Compact: Saves installation length by 40% compared to flanged valves.
Lightweight Design: Easier to handle and transport.
Soft Sealing Gate: EPDM encapsulated gate for zero leakage.
Low Torque Operation: O-ring stem seal reduces operating force.
Cost Effective: Fewer bolts and no flange gaskets required.

Socket End Connection: Push-on joint design compatible with ductile iron pipe (ISO 2531/EN 545).
Quick & Easy Installation: No bolts or gaskets needed — simply push pipe into socket.
Zero Leakage Guarantee: Resilient seated gate provides bubble-tight shut-off.
Anti-Pullout Design: Integral locking ring prevents accidental disconnection.
Corrosion Resistant: 250-micron epoxy coating inside and out.
Ideal for Buried Service: Non-rising stem design saves vertical space.

Flanged Ends: Integral flanges for direct bolt-up to pipeline flanges (PN10/16/Class 150).
Robust Construction: Designed for higher torque and more demanding service.
Full Rubber Lining: Seat is fully bonded to the body for corrosion resistance.
Easy Disc Replacement: Remove top flange and replace disc without dismantling valve.
Gear or Motor Ready: Top flange conforms to ISO 5211 for actuator mounting.
Bi-Directional Sealing: Zero leakage in either direction.

Lug Type Body: Threaded inserts on both sides allow dead-end service.
Removable Downstream Piping: You can remove downstream pipe without shutting off upstream pressure.
Double Flanged Bolt Pattern: Bolts pass through lugs, not through the body.
Soft Seat: EPDM or NBR rubber-lined body for bubble-tight sealing.
Bi-Directional: Rated for full pressure in both directions.
ISO 5211 Mounting Pad: Easy to install actuators.

Single Orifice Design: Small continuous air release during pressurized operation.
Compact Size: Smaller and lighter than double orifice type — fits tight spaces.
Suitable for Pumped Lines: Releases air entrained by pumps.
Prevents Air Binding: Eliminates air pockets that cause flow reduction.
Threaded Connection: Easy to install on small branch lines.
Automatic Float Operation: Maintenance free.

Simple Rubber Flap Design: No springs, no hinges — just a flexible rubber flap.
Silent Operation: Rubber flap eliminates metal-to-metal slamming noise.
Corrosion Proof: All wetted parts are rubber or epoxy-coated ductile iron.
Ideal for Dirty Media: Handles sewage, sludge, and water with solids.
Low Cracking Pressure: Opens with minimal forward flow.
Maintenance Free: No moving parts to lubricate or replace.

Flanged Swing Design: Traditional robust construction for large diameter pipelines.
Low Pressure Drop: Disc swings fully open — minimal flow restriction.
Lever & Weight Option: External counterweight reduces slamming and allows adjustable closing speed.
Renewable Seat Ring: Seat can be replaced without replacing the entire valve.
Horizontal or Vertical (Upward Flow) Installation: Flexible mounting.
Class 125/150 or PN16: Meets major international flange standards.
