Resilient Seated Knife Gate Valve – FAQ
A resilient seated knife gate valve is a valve with a flexible, elastic seat that ensures tight sealing and leak-free operation. It is designed for low- to medium-pressure applications and is ideal for controlling liquids, semi-solids, and low-abrasive slurries.
Unlike metal-seated valves, resilient seated valves use an elastic seat made from materials like EPDM, NBR, or PTFE. This provides better sealing for low-pressure applications, reduces operating torque, and minimizes wear on the gate.
Standard sizes range from 2" to 48" (DN50–DN1200), with pressure classes including PN10, PN16, ANSI 150–300. Custom sizes and pressure ratings can also be supplied based on project requirements.
Body Materials: Cast iron, carbon steel, stainless steel, or duplex steel.
Gate Materials: Stainless steel or alloy steel for abrasion and corrosion resistance.
Seat Materials: Resilient materials such as EPDM, NBR, or PTFE, chosen based on media type, temperature, and chemical compatibility.
These valves can be operated manually, via gear mechanism, or actuated pneumatically, hydraulically, or electrically, depending on your system requirements.
Yes. The reinforced gate and resilient seat design make them suitable for low- to medium-abrasive slurries, liquids, and semi-solid media in industries such as wastewater treatment, pulp & paper, mining, and chemical processing.
