Product Overview

The Rising Stem Knife Gate Valve is a rugged and reliable valve designed to isolate and regulate the flow of abrasive, viscous, or solid particle laden media in a variety of industrial applications. The valve features a rising stem design that clearly indicates valve position (open or closed) during operation. The sharp knife gate valve easily isolates viscous, solid or slurry media and is an ideal solution for applications such as mining, wastewater treatment and pulp and paper.

The lifting lever mechanism ensures smooth operation, which is especially beneficial when frequent valve position adjustments are required. The valves are available in a wide range of sizes, materials and configurations, providing flexibility to meet specific application requirements.

Product Characteristics

Rising stem design: When the valve opens, the stem rises above the valve body to clearly indicate the valve position. This feature is essential to ensure the safety and operational efficiency of manual or automatic systems.

Knife gate design: The gate is designed with a sharp knife edge to cut through thick, viscous or solid-particle-laden media. This ensures tight closure even when handling slurries, slurry materials or abrasive substances.

Durable structure: the valve is made of carbon steel, stainless steel and cast iron and other high-strength materials, with excellent corrosion and abrasion resistance, to ensure long-term reliable operation in harsh working environments.

Multiple Sealing Options: The valve is available with a variety of sealing materials, such as rubber, PTFE, or metal seals, to provide optimum sealing results depending on the nature of the media and operating conditions.

Wide range of sizes: The valves are available in sizes from DN50 to DN1200 and are suitable for different sizes of pipes and applications, including large diameter systems.

MANUAL OR AUTOMATIC OPERATION: The valve can be operated manually with a handwheel or driven with an electric, pneumatic or hydraulic actuator for both manual and automatic processes.

Product Advantages

Clear Position Indicator: The rising stem design provides a visual indication of the valve position, ensuring easy operation and reducing the risk of misuse. This is particularly beneficial in environments where manual operation or automated control is not possible.

RELIABLE ISOLATION: The knife gate valve mechanism ensures reliable, tight shutoff even in solid, abrasive or viscous media. The sharp gate minimizes friction and wear, enabling the valve to maintain a firm seal for long periods of time.

Adaptable: The valve is suitable for all types of media, including slurries, wastewater, chemicals, and fluids that are thick or contain solids, making it widely used in industries such as mining, pulp and paper, wastewater treatment, and chemical processing.

Low maintenance: Thanks to their durable materials and simple, efficient design, rising stem knife gate valves are virtually maintenance-free, reducing downtime and operating costs.

Installation Flexibility: The valve is available with flanged or lugged connections, providing flexible installation options for easy integration into new or existing piping systems.
