DSS Valves products

The DSS Severe Service Knife Gate Valve (SSKGV) is engineered for high-pressure applications where reliability and endurance are critical. Featuring a unique Guided Shear Gate design, this valve combines a shearing tip with internal gate guides to effectively cut through various media, including solids, scale, fiber, and paste. Extensively tested and adhering to API, ASME, and MSS specifications up to ASME Class 1500/PN 250 with the capability to go higher, the SSKGV ensures zero leakage in bi-directional flow. The valve is built to mitigate common issues such as pipe turbulence, erosion, and leakage while maintaining structural integrity under severe service conditions. DSS Valves also offer extensive actuation options, including pneumatic, hydraulic, electric, and electro-hydraulic systems, customized to meet specific user requirements. This high-performance valve is widely applicable in industries including mining, oil and gas, chemical processing, pulp and paper, and more.

The DSS Double Block and Bleed Valve integrates all the features of their Guided Shear Gate design while being fully compliant with MSS-SP-152 standards. This valve is engineered to ensure bi-directional zero leakage, handling conditions from full vacuum up to ASME Class 1500 / PN 250 (3750 psig / 250 barg). It streamlines operations by eliminating the need for multiple valve systems, which results in savings on cost, time, and space. The valve excels in severe service environments and offers enhanced reliability in isolation tasks. DSS Valves are reputed for their robustness and longevity, equally effective in both extreme and general applications, contributing to lower overall ownership costs by reducing downtime and extending service life. This makes them a preferred choice across industries such as mining, oil & gas, power generation, chemical processing, and wastewater management.

DSS Valves specializes in severe service valves for various industrial applications. Their M81 Knife Gate Valve is designed specifically for low pressure settings while still maintaining robust performance. Engineered to meet MSS SP-81 standards, the valve ensures bi-directional zero leakage isolation. The valve's Guided Shear Gate design allows it to cut through scale, fibers, and other solids within the pipeline, a common requirement in industries such as mining, oil and gas, power, chemical, municipal services, steel manufacturing, pulp and paper, and wastewater treatment plants. Made from 316 stainless steel, it features a full round port, flat face flange, and front and back flush-outs. With the same core functionality as the more heavy-duty models, the M81 KGV is a cost-effective, reliable solution for applications not demanding high-pressure capabilities.

The DSS Severe Service Check Valve (SSCKV) is designed to provide reliable non-return function in demanding applications where traditional check valves typically fail. Leveraging decades of expertise in severe service valve engineering, the SSCKV addresses common failure modes such as leakage and material corrosion, ensuring zero leakage performance even under high pressure and temperature conditions. All components of the SSCKV are sourced from U.S.-based suppliers and the final assembly occurs in Niles, Michigan, making it fully compliant with American Iron and Steel (AIS) provisions and the Buy American Act (BAA). This advanced check valve is ideal for applications in various industries including chemical, mining, oil and gas, and wastewater where non-return functionality is crucial to prevent pump damage and maintain process efficiency.

DSS Valves is breathing new life into the traditional Through Gate Valve by combining it with our technologically advanced Guided Shear Gate Design. The SSTGV displaces media into its port while closing, and releases it back into the stream when in an open position. This makes the Through Gate a perfect solution to static columns and applications with large amounts of solids in the pipe.
