The “double block and bleed” knife gate valve was specially developed for applications using hazardous media. The DB model is a single valve with two seat areas. In the closed position, these provide a seal against pressure from both ends of the valve, and there purge ports to flush the cavity between the seat areas. The DB model thus makes complex and costly multiple valve systems redundant. In spite of these cost benefits, it offers zero leakage protection in difficult applications.
Nominal sizes: 50 – 400 mm
Material: Stainless steel, Cast iron, Ductile iron, Cast steel, Special material

The HD series is an extraordinary development of the Wey knife gate valve for operation up to a maximum pressure of 100 bar. The ingenious design ensures that the pressure of the medium creates an automatic sealing effect inside the seat area. The special bonnet design also allows media containing solids to be flushed out – and, of course, it is completely airtight. This makes the HD series ideal for the most difficult applications.
Nominal sizes: 65 – 400 mm
Material: Stainless steel

Design: Check valve
Case shape: Double flange body
Nominal sizes: 65 – 300 mm
Our RSK check valve is our comprehensive answer to today’s demanding requirements. We have paid special attention to the robust design. The main difference compared to conventional check valves is that the valve disc and lever are not inside the body, but inside the cover, making it very user-friendly. Moreover, once the cover is removed, the valve body is fully exposed for any kind of inspection, even when it’s still installed in the system.
Design: Check valve
Case shape: Double flange body
Nominal sizes: 150 – 400 mm
The TK01 is an eccentric, non-return check valve manufactured in accordance with DIN face to face length EN 558/ISO 5752 series 14. When the butterfly valve opens and closes, the eccentrically mounted valve disc swings in and out at an optimal angle. Unlike conventional check valves, the TK is very free-moving and opens with minimal differential pressure. This is because the contact pressure in the seal seating has been optimized. Thanks to its robust, careful design, the TK has proven itself on the market over the course of decades.
Design: Double eccentric butterfly valve
Case shape: Double flange body
Nominal sizes: 100 – 400 mm
The TZ01 is our double eccentric butterfly valve. The specially developed dynamic seal is self-pressing and adapts to system pressure. Only as much system pressure is generated from the seal on the seat as is necessary for the drip-tight seal, due to the respective operating pressure at the time. This results in a minimal amount of torque required for actuation. The special shape of the seal means the direction of pressure can come from both sides.
Design: Sluice gate
Width: 200 – 5000 mm
Head of water: 0 – 15 m
Our type 2, 3, and 4 sluice gates are all based on the same well thought-out design principle. Every one of our sluice gates is custom-made with great care. Thanks to the circumferential transverse seal and double scraper, our sluice gates are much tighter than the standard prescribes – and are tight in both flow directions.
Design: Sluice gate
