Pneumatic Knife Gate Valve

When industrial pipelines require automated isolation across large line sizes, a valve needs to combine practical gate movement with a suitable operating mechanism. The Pneumatic Knife Gate Valve from SVI is designed for this purpose, using pneumatic actuation to operate the knife gate while providing a stainless steel construction and lug-end connection. With a size range from 50 mm to 1000 mm and a specified pressure of 7 kg, it is configured for a variety of industrial installation requirements.

Pneumatic Movement for Efficient Flow Isolation

A knife gate valve works by moving a sharp-edged gate through the flow passage to establish an open or closed condition. In the pneumatic version, compressed air is used to operate the actuator, reducing dependence on manual force and allowing the valve to be incorporated into an automated operating arrangement.

The SVI configuration is particularly suited to industrial systems where remote operation, repeatable valve movement or reduced manual intervention is desirable. The stainless steel construction provides a durable material option, while the lug-end arrangement supports installation in suitably designed flanged pipeline systems.

Key Characteristics of the Valve

• Pneumatic actuation: Uses compressed air to operate the gate and support automated isolation.
• Stainless steel construction: Provides a robust valve material for suitable industrial environments.
• 50 mm to 1000 mm range: Covers a broad selection of pipeline sizes for different installation requirements.
• Lug-end connection: Offers a practical connection arrangement for compatible piping and flange assemblies.
• 7 kg pressure specification: Intended for operation within the stated pressure limit.
• Industrial application: Configured for use in appropriately selected industrial process and utility systems.

How the Pneumatic Knife Gate Arrangement Works

During operation, compressed air is supplied to the pneumatic actuator, producing the mechanical force required to move the valve gate. Depending on the control arrangement, the actuator can be operated from a remote station or integrated with an automated plant control system. The gate then travels across the valve passage to establish the required flow condition.

This operating principle can be advantageous in installations where valves are positioned at elevated locations, within larger process networks or in areas where frequent manual access is inconvenient. Proper pneumatic supply and actuator configuration should be considered during valve selection.

Size Flexibility for Industrial Installations

The broad 50 mm to 1000 mm size range allows the SVI Pneumatic Knife Gate Valve to be considered for both relatively compact lines and large-diameter industrial pipelines. Selection should be based on the actual line size, operating pressure, process media, temperature, installation arrangement and required actuation duty.
