Full Port Knife Gate Valve

The WIVO-series Full Port Knife Gate Valve is a bi-directional wafer-style valve primarily designed for handling highly concentrated flow media. Featuring a through-going O-port plate, this valve ensures reliable and secure shut-off performance, even in demanding applications, without the risk of clogging. Its double-seat construction enables it to efficiently manage flow in both directions, making it a versatile choice for various industrial systems.

The WIVO-series Full Port Knife Gate Valve is a robust and reliable bi-directional valve, ideal for use in industries such as pulp & paper, water treatment, and power generation. Available in sizes ranging from DN50 to DN600, it supports temperatures between -29°C and +800°C and pressures up to 10 Bar. Constructed from carbon steel, stainless steel, or special alloys, it features a hard chrome-coated, polished gate and replaceable seats for excellent sealing performance and durability. Designed to meet MSS SP-81 and international flange standards, it offers efficient and leak-free operation.

Product Features:

Body:

Full Port Design: The full port design reduces pressure drop and enhances flow capacity, ensuring efficient operation.

Leak-proof Packing: Packing on both the top and bottom of the valve prevents any leakage to the surrounding area, improving reliability.

Gate:

O-port Gate Design: The gate features an O-port cut that allows media to flow through while closing, preventing clogging in the valve body. The gate returns this section when the valve opens.

Increased Gate Thickness: The gate can be thickened to accommodate higher working pressures, offering added durability.

Polished Gate Surface: Both sides of the gate are finely polished to ensure a tight seal and minimize jamming.

Hard Chrome Coated: The gate is coated with hard chrome for superior abrasion resistance, extending the valve's lifespan.

Seat:

Replaceable Side-entry Seat: The seat is easily replaceable, reducing maintenance costs.

Seat Retainer: The seat retainer covers the seat's side, protecting it from direct flow flushing and extending its service life.

Adjustable Preloaded Seat: The preloaded seat is adjustable to provide different sealing classes and compensate for normal wear.

Dual-side Seats: With seats on both sides, this valve is fully capable of handling flow in both directions with complete efficiency.

Other:

Double Thrust Bearing: The inclusion of double thrust bearings minimizes operating torque, improving ease of operation and reducing wear.
