Our resilient seated ball valves are specifically designed to meet the demanding needs of hydroelectric applications. We offer one of the largest selections of products combined with outstanding customer service.

Leaders in design and manufacture of  valves for the hydro-power industry

Slurry Tuff is a leader in the design and manufacture of zero-leakage, high-performance isolation valves for the hydro-power industry.

Specializing in both hydro-electric and pumped storage applications, Slurry Tuff Dams & Reservoir Valves are engineered to provide superior leak tightness for long service life. Our engineering department has been designing and manufacturing these isolation valves for over 30 years.

Designed to meet the demanding needs of hydroelectric applications

Our resilient seated ball valves are specifically designed to meet the demanding needs of hydroelectric applications. Resilient seated ball valves are used in dams and reservoirs, hydroelectric power stations and other places where water is being transferred from one location or body to another.

These valves can withstand high pressures exerted by water that flows at great speeds from one place to another. They also have an extremely low coefficient of friction which allows for smooth operation under these conditions. Resilient seated ball valves have been used for over 100 years with no major issues since then, making them a great choice for your project.

Slurry Tuff : Your number one choice for zero-leakage and high cycle operation

Slurry Tuff is your number one choice for zero-leakage and high cycle operation, even with critical services such as full vacuum or double block and bleed. Our resilient seated ball valves are specifically designed to meet the demanding needs of hydroelectric applications. A variety of materials can be used at all temperature ranges.

Slurry Tuff’s resilient seated valve design offers a unique solution for the most challenging service conditions by creating a positive seal between seat and plug (or body), resulting in superior quality shutoff under all conditions. The resilient material provides excellent wear resistance, protects against erosion damage and assists in maintaining sealing integrity over time by reducing wear on seal components caused by hydraulic fluid pressure fluctuations.

Isolation valves are available in all major valve materials

Slurry Tuff isolation valves are available in all major valve materials, sizes from 2″ to 60″ and with ANSI Classes from 150 to 2500. Other features include: high cycle life, zero leakage and full vacuum capability.

Dam & Reservoir Valves: Designed for Zero Leakage

Designed for Zero Leakage – Class VI Shutoff – 100% tested prior to shipment.

Slurry Tuff is a leader in the design and manufacture of zero-leakage, high-performance isolation valves for the hydro-power industry. Our Slurry Tuff isolation valves are designed to operate under extreme conditions including: high pressures, large temperature gradients and/or flow velocities. These valves can be used to isolate turbine generators from pipelines or on new or existing projects where replacement may not be feasible due to space constraints or cost considerations.

Designed for High Cycle Life – minimal seat wear due

The seat design is proprietary, but it’s designed for minimal seat wear. You can expect a long cycle life from your valve.

In addition to this, the valves are designed so that they will fit snugly into your pipe and will not fall out like other valves on the market. This keeps you from having to constantly re-tighten them after use or worry about damaging pipes when removing them.

Built on the end user’s experience – Not just an off-the shelf product.

Since Slurry Tuff Dams & Reservoir Valves were introduced in 2005, they have been continually developed based on feedback from our customers. Their engineers work closely with customers to develop new products and to improve existing products. They know how to conform their products to meet the exacting requirements of the industry in order to ensure that every customer gets exactly what they need.

We assure our customers receive their products when they need them
