The robust design of the valve minimises pressure losses, making the WS112 ideal for handling large volumes of water. This series combines the highest technical standards with a flow-optimised design, ensuring efficiency and reliability in water supply and treatment.
Robust and durable under harsh conditions
The double eccentric design of the WS112 reduces friction, extending the service life of components—even in demanding applications with extended maintenance intervals. Featuring a seal-on-disc design, this valve ensures a bidirectional, leakage-free seal. Available in double-flange configuration, the WS112 also features an innovative polygon shaft profile, optimizing torque transmission to the disc. The actuation type can be flexibly adapted to customer-specific requirements.
Wide range of applications and customised options
Designed to meet diverse water infrastructure needs, the WS112 is available in a variety of pressure ratings and sizes. Whether it’s municipal water networks, wastewater treatment, or seawater desalination, this valve delivers efficiency and adaptability, setting new benchmarks in performance
Quality in detail
1 - BODY
The heavy-duty body construction is equipped with integral lifting points for easy installation, while the brackets provide strong ground support.
2 - DISC DESIGN
The low-profile, streamlined disc design ensures high Kv values, while the double-offset design reduces seal wear and torque. The key-less disc-shaft connection and closed-end disc with advanced shaft sealing system ensure corrosion-free operation.
3 - TOP FLANGE
All valves feature ISO top-flanges for direct mounting of various actuator and operator connections.
4 - BEARING SYSTEM
Self-lubricating bearings reduce shaft friction by centralizing the shaft and preventing radial movement from actuator side-thrust, resulting in low operating torque and ensuring smooth operation.
5 - RETAINING RING
The one-piece retaining ring prevents the sealing ring from rolling out, while the sealing ring can be easily replaced on-site without dismantling the valve disc or requiring any special tools.
6 - SEAT
EPDM, NBR, FPM seals provide bi-directional zero-leakage sealing.
7 - SHAFT
The dry shaft design, featuring precision bearings, O-rings, and sealed, self-lubricating bearing bushes, fully isolates the stainless-steel shafts from the medium, ensuring maintenance-free operation throughout their lifespan. The polygonal design reduces hysteresis, enhancing overall efficiency.
8 - ENCLOSED DISC HUBS
Durability is enhanced by enclosed disc hubs that provide uninterrupted corrosion protection.
9 - POLYGON CONNECTION
The polygonal design eliminates hysteresis, providing seamless, effi cient movement without any energy loss, thereby enhancing system performance.
10 - BODY SEAT
The stainless-steel weld-filled integral body seat, engineered with a high-precision finish, delivers a corrosion- and erosion-resistant surface to ensure durability and reliability of the entire sealing system.
Applications of the WS112
The WS112 is designed for versatile applications and is used in numerous areas:
- Drinking water pipes and supply networks: Reliable and hygienic solution for municipal utilities and supply companies.
- Seawater desalination plants: Corrosion-resistant construction for long-term use in salty environments.
- Wastewater treatment and greywater management Perfectly suited for wastewater treatment plants, treatment facilities and sewer networks.
- Power plants and industrial facilities: Efficient control of water and process water in energy and industrial infrastructures.
- Pumping stations & underground transport lines: Safe handling of large volumes of water over long distances.
