Because sometimes speed is crucial...
Shortly before Christmas, we received an emergency call from Räber AG. In an almost new plant for jam production, a knife gate valve (third-party product) had suddenly failed. Within a few hours, our team was able to react and by the next morning, the jam manufacturer received a custom-fit Wey knife gate valve VNC DN400 for his plant. A service like this is a question of attitude for us and a real team effort.
Did you know that our valves are available in DIN, ANSI, BS, and AS flange drillings? We also offer a wide range of nominal sizes, face to face dimensions and materials. Let us create the perfect configuration for your needs.
Safety-cylinder for chemical industry
Safety first! Unlike most of our valves, this knife gate valve MGC DN 300 is equipped with a single-acting cylinder. Whenever the compressed air in the production plant fails, the valve closes automatically to prevent further damage. The cylinder has a tandem design with two pistons and therefore a reduced diameter. The valve in the photo was recently produced for a german customer in the chemical industry. It is ATEX certified for zones 0/20 (inner area) and 1/21 (outer area).
Heavy duty valve in O-Port gate design
Unlike most Wey knife gate valves, our DP series is designed with a through gate. This allows the valve to cut through static medium columns. For the valves in the picture, we additionally used hardened steel to provide extra protection against corrosion and PTFE as a non-stick coating. The three through gate valves withstand temperatures of up to 200°C and a pressure of more than 20 bar. They will be installed at a plant producing fire protective boards in Belgium.
A total of 800 wastewater treatment plants and 50‘000 km of sewer lines ensure the high water quality of Switzerland‘s rivers and lakes. Wey valves can be found in more than 700 of these plants. We have been at home in wastewater treatment for almost 50 years and are therefore experienced with the specific challenges of water treatment applications.
Think big! Wey MFH DN 1600
This huge knife gate valve with a nominal size of DN 1600 and a hydraulic actuator was recently produced for our partner EIP Enviro Level Controls Pvt Ltd in India. It will be installed on the production site of one of India‘s largest steel manufacturers. Due to its ceramic sealing and Bricafeu 479 coating, it is heat-resistant up to 230°C.
Preventing imminent power outages with gas-fired power plants
The Federal Council is currently discussing how Switzerland can protect itself from a sudden blackout. The SRF reports about the different possibilities and the block-type thermal power plant in Mellingen. Like many other plants around the world, this power plant is equipped with Wey valves.
Faster than the explosion and hygienic for all requirements of the pharmaceutical and food industry
Our high speed isolation valve «SpeedWey» closes within 23 milliseconds in case of an explosion and protects the rest of the pipe system against destruction. The valve in the picture is additionally fitted with a PTFE inliner, which guarantees smooth surfaces with virtually no crossovers or gaps. It can therefore be used for the pharmaceutical and food industry and protect the facility and human life e.g. from flour dust explosions. The SpeedWey is manufactured at our production site in Switzerland and exclusively available at our partner IEP-HOERBIGER Technologies.
Energy from biomass
A new documentary of the NDR talks about the energy source biogas, visiting one of northern Germany's biggest biogas plants in Torgelow. The plant is fully equipped with Wey valves.
For high pressures up to 100 bar
In means of handling extremely high pressures and dealing with abrasive, thick and dry media, our knife gate valve HD is our front-runner. Our engineering team designed it with an automatic sealing effect: The higher the pressure, the better the seal. The valve shown in the photo has a nominal size of 350 mm and is leaving for a mine in Australia next week.
Every single one of our water control gates is custom-made in our production site in Eschenbach, Switzerland. Our team often visits the operating sites serveral times to make sure everything fits. Today Wey water control gates are found all over the country in water and wastewater treatment, power generation, and irrigation systems.
Smart actuators for high performance valves
For a special order from China, our valves were upgraded with electrohydraulic actuators.
Sistag mechanic - an adventurous job
Our valves get installed at extraordinary places all over the world. This means always new challenges for our assembly team.
