Product Overview

The Manual Knife Gate Valve is a rugged, manually operated valve designed to isolate abrasive and viscous fluids in pipelines. The valve is ideally suited to industries that require efficient flow control in harsh conditions, such as mining, wastewater treatment, chemical processing and paper mills. Its sharp gate plate is specially designed to cut through thick slurries, sediments and viscous media, ensuring a tight seal when closed and reliable shutoff performance.

Manual operation makes them easy to control in a variety of applications and is a cost-effective and durable low-maintenance solution. Designed for use in harsh environments, manual knife gate valves provide safe isolation and prevent backflow to improve operational efficiency and minimize downtime in fluid systems.

Product Characteristics

MANUAL OPERATION: The valve is operated by a handwheel or gearbox, which allows precise control of the valve operation in the open and closed positions. Manual operation requires no external power supply, ensuring easy and reliable operation.

KNIFE GATE DESIGN: Sharp gates designed to cut through viscous, abrasive slurries and solid particles for effective cutoff.

Sealing Options: The valve can be equipped with either a resilient soft seal or a metal-to-metal seal for optimum sealing performance, depending on the application.

Durable structure: manual knife gate valve is made of carbon steel, stainless steel or cast iron and other high-quality materials, corrosion-resistant, wear-resistant, long service life.

Wide range of sizes: The valve is available in sizes from DN50 to DN1800 to accommodate a wide range of pipe diameters.

Compact and robust design: Despite the valve's power, its space-saving design makes it suitable for installation in confined spaces.

Product Advantages

Cost-effective: Manual operation without actuators reduces initial installation costs and maintenance.

Reliable performance: knife gate valve sharp knife edge can effectively cut hard media to ensure tight sealing and reliable closure.

Low maintenance costs: manual operation and simple design minimize the risk of failure, thus reducing maintenance requirements and downtime.

Wide range of applications: The valve can handle a wide range of harsh media, including slurries, sediments and chemicals, making it highly versatile in different industries.

Small footprint: The compact design is ideal for space-constrained installations without compromising performance.
