NRS Knife Gate Valves

The WIVO VALVES Pneumatic Cast Iron Knife Gate Valve (DN300) is a high-performance industrial valve designed for efficient flow control in slurry, abrasive, and viscous media applications. Its robust cast iron construction ensures durability, while the pneumatic actuation provides quick and reliable operation.

The WIVO VALVES® DN200 Resilient Seat Gate Valve is engineered for superior performance in water supply, irrigation, and industrial pipeline systems. Crafted from high-quality ductile iron with a soft EPDM/NBR sealing seat, this valve ensures leak-free operation, exceptional durability, and effortless maintenance. Designed for PN10/16 pressure ratings, it is ideal for fully open or fully closed applications where reliable flow control is critical.

The WIVO DN100 Double Flanged Cast Iron Gate Valve is designed for reliable shut-off applications in water, oil, gas, and other general industrial services. Its robust construction ensures durability and leak-free performance in demanding environments.

The Ductile Iron Knife Gate Valve DN300 is engineered for efficient isolation and flow control in demanding industrial applications. Designed for slurry, wastewater, and abrasive media, this valve features a sharp blade mechanism that cuts through thick fluids, ensuring reliable sealing and minimal clogging. With a robust ductile iron (GGG50) body, the DN300 knife gate valve is ideal for mining, chemical processing, pulp & paper, and water treatment plants. Its bidirectional sealing capability and low-maintenance design make it a cost-effective solution for high-pressure and high-solid environments.

The eccentric butterfly valve is a type of valve that uses an eccentric disc to control the flow of fluids. This valve is designed to offer excellent sealing performance and durability, especially in high-pressure and high-temperature applications. Its unique design ensures minimal wear on the sealing surfaces, making it highly reliable in environments with abrasive, corrosive, or viscous fluids. Eccentric butterfly valves are commonly used in industries such as chemical processing, power generation, and wastewater treatment.

The Corrosion-Resistant NRS Knife Gate Valve is engineered for handling aggressive and corrosive media, making it an ideal choice for industries such as chemical, petroleum, pharmaceutical, metallurgy, and wastewater treatment. Featuring a non-rising stem (NRS) design, this valve offers exceptional sealing performance and reliable operation, especially in systems with corrosive fluids or slurries.
