Uni - Directional Seal Wafer End Pneumatic Knife Valve , MSS-SP DIN Standard Single Acting Valve

MSS-SP DIN Standard Single Acting Pneumatic Uni-directional Seal Wafer End Knife Valve

Description

One-piece cast body with guides to support gate and seat wedges. Provides high flow rates with low pressure drop. Various seat and packing materials available. Face to face dimension in accordance with MSS-SP-81 standard. And arrow is marked on the body indicating the flow direction.

General Applications

The TEKO knife gate valve is used for liquids that contain a maximum of 5% suspended solids. If it is used for dry solids in gravity feed applications, it should be installed with the arrow on the body pointing in the opposite direction to the flow.

Max. Working Pressure

The mentioned working pressures are just valid for the pressures applied on the direction of arrow marked on the body. As the valve is designed with gate support guides, the valves are able to support a 30% of these pressures from the opposite direction without any damage on them. In these cases, the valves are not 100% water tight. To obtain total water tightness in these conditions, it is necessary to incorporate additional supports.

Advantage of TEKO uni-directional seal

• Special uni-directional design contains internal guides that support the knife gate and allow it to work under back-pressure of 30%.
• Independent stem protection can be unstalled easily and lubricant regularly
• Nodular Cast iron handwheel reduce the breakages during operation.
