The HCPZ-series Stainless O-port Knife Gate Valve is a bi-directional wafer knife gate valve. It is mainly designed for highly concentrated flow media. With a through going O-port plate, this valve provides a stable and safe shut-off performance without clogging. With double-seat design, it can handle flow in both directions.
Features 1. Body a) Full port design minimizes pressure drop and maximizes flow capacity. b) Packing at both top and bottom eliminates leakage to surrounding.

Features 1. Body a) Full port design minimizes pressure drop and maximizes flow capacity. b) Packing at both top and bottom eliminates leakage to surrounding.
2. Gate a) Though gate with o-port cut through a disc of media down when closing and return this portion back when opening. This prevent media from clogging in the valve body cavity. b) Gate thickness can be increased to handle higher working pressure. c) Gate surface is well polished at both sides for tight seal and less jamming. d) Gate is hard chrome coated for better abrasion resistance.
3. Seat a) Side-entry seat is replaceable, reducing the cost of maintenance. b) Seat retainer covers the side of seat and prevents seat from direct flow flushing. c) Preloaded seat is adjustable to meet different sealing class and compensate normal seat wear. d) With seats on both sides, valve can handle flow in both directions 100%.
4. Other a) Double thrust bearing minimizes the operating torque.
