Open stem knife gate valve

Product Overview

The Bonnetless Knife Gate Valve is a high performance valve designed for isolation applications where slurries, viscous fluids and solids are cut efficiently. Unlike traditional bonneted knife gate valves, the bonnetless design eliminates the need for a bonnet assembly, providing a more compact and economical solution. The valve is ideally suited for low to medium pressure system applications, especially in industries such as wastewater treatment, mining, pulp and paper, and chemical processing.

By eliminating the bonnet, the bonnetless knife gate valve simplifies valve construction, reduces weight, and improves ease of maintenance. The valve blade is made of high-strength, corrosion-resistant material that cuts through difficult media with ease, ensuring reliable and durable service even under harsh conditions. The valve is particularly suitable for applications where space is limited but performance is still required.

Product Characteristics

Streamlined design: Eliminating the bonnet reduces the overall size and weight of the valve, making it easier to install and maintain. The streamlined construction also reduces material costs and installation complexity.

EFFICIENT BLADE CUTTING: The knife gate blade is designed to cut slurries, viscous liquids and solids with minimal resistance. It is made of robust materials such as stainless steel or carbon steel to ensure long-lasting performance even in harsh and abrasive environments.

Compact and Lightweight: The bonnetless design makes this valve a more compact and lightweight solution, providing better flexibility for applications with space or weight constraints.

DURABILITY AND CORROSION RESISTANCE: The valve body is usually made of high quality materials such as carbon steel, stainless steel or ductile iron, which are corrosion and abrasion resistant. This is essential for handling aggressive, corrosive or abrasive media.

Flexible sealing options: The valve can be equipped with a variety of sealing options, including PTFE, rubber and metal seals, depending on the specific application requirements. This versatility ensures reliable sealing even when handling abrasive, corrosive or high temperature media.

Low Pressure Design: The bonnetless knife gate valve is designed for low to medium pressure applications and is ideal for applications where high pressures and temperatures are not a concern. They are available in pressures up to PN10 or PN16.

Multiple Connection Types: The valve is available in a variety of connection types, including flanged, butt-clamp, and lugged, for flexible installation in a variety of piping configurations.

Product Advantages

ECONOMICALLY EFFICIENT: Simplified design reduces material costs and installation time, making it a more economical choice than traditional valves with bonnets.

Compact and lightweight: smaller size and lighter weight make it easier to maneuver, install and operate in narrow spaces or tight spaces.

RELIABLE AND EFFICIENT: Designed for handling difficult media such as slurries, abrasives and viscous fluids, this valve provides reliable and efficient performance.

Lower maintenance costs: With no bonnet and fewer components, there are fewer points of failure, simplifying maintenance and reducing downtime.

Sealing Flexibility: A wide range of sealing materials are available to meet specific application requirements for increased reliability and performance.

Cost and Space Savings: The bonnetless design provides a more compact solution without sacrificing reliability, making it ideal for space-constrained and cost-conscious projects.
