ABSTRACT:
A gate valve assembly has two aligned and connected body housing members which each have a gate slot above a through passage which is above a seat portion slot. Gaskets are compressed by the body housing members to form a liquid-tight seal along the valve sides. Two resilient valve liners are fitted between and compressed by the body housing members. Each valve liner has a body with a planar front face and a cylindrical through passage which extends through the liner body. A seat portion extends downwardly from the body of each liner and increases in thickness as it extends from the body. The valve liners are compressed within the body housing members such that the planar front faces are adjacent one another and the seat portions are compressed within the seat portion slots to produce a tight seal along the bottom of the valve assembly. A packing filled chamber at the top of the assembly forms a tight seal at the top of the valve. An imperforate gate is slidable through the gate slots to alternatively obstruct and permit fluid flow through the valve. The seat portions extend to the bottom of the valve such that particles trapped between the seat portions may be expelled form the valve between the seat portions.
