Abstract
A valve to control abrasive fluids under high pressure has a plastic seat. A circular ridge peripherally formed on the valve cartridge sealingly engages the seat. A means is provided within the valve cartridge to support the seat axially and radially. The diameter and taper of the poppet match those of a mating recess in the seat.
