This component is used in the following industrial products
A type of valve that uses a disc or cone-shaped element (poppet) to control fluid flow by lifting perpendicularly from its seat.
A safety device installed on a distribution manifold/block to prevent overpressure by automatically releasing excess fluid when pressure exceeds a preset limit.
A sealing and flow control assembly for rapid-activation valve banks, combining a poppet valve with integrated sealing elements.
A practical evidence checklist for RFQ preparation and supplier evaluation.

The primary function is to create a reliable seal against the valve seat to control or stop fluid flow in poppet valves.
Consider fluid compatibility, operating temperature, pressure requirements, corrosion resistance, and wear characteristics. Common choices include stainless steel for corrosive environments and PTFE for chemical resistance.
Regular inspection for wear, surface damage, or deformation; cleaning to prevent contamination; and replacement when sealing performance degrades beyond acceptable limits.
