Straight-through Diaphragm Valve Features

The straight-through diaphragm valve features a design where the diaphragm rises when the valve is opened, allowing smooth flow in any direction. When closed, the diaphragm creates a tight seal, ensuring complete closure even in the presence of gravel or fiber in the pipeline. Unlike weir diaphragm valves, this valve requires a diaphragm with greater elasticity, which limits the range of materials that can be used for the diaphragm.

1. Corrosion Resistance

Our diaphragm valves are ideal for applications requiring corrosion resistance. With an extensive range of linings and diaphragms, they can be tailored to suit various needs, providing an effective and economical solution without relying on exotic alloys. Available linings include elastomers and fluoropolymers, specifically designed to combat corrosion in harsh environments.

2. Abrasion Resistance

Thanks to our advanced polymer technology, these diaphragm valves offer superior abrasion resistance. Capable of handling up to 100% solids, the valve, combined with a soft rubber diaphragm, ensures a tight shut-off, meeting the standards of MSS SP-88 and BS EN 12266-1.

3. Leak Tight

Our diaphragm valves are engineered for 100% leak-tight performance in pressure and vacuum services. They maintain leak-tight operation even after thousands of cycles, significantly reducing processing and handling costs by preventing emissions that are typically associated with other valve types. All working parts are isolated from the line media, ensuring positive closure, even with frequent cycling or entrained particulates.

4. Easy Maintenance

The three-part design allows for easy maintenance and actuator retrofitting without the need to remove the valve body from the pipeline. This feature reduces the overall cost of ownership compared to other valve types, making maintenance simple and cost-effective.

5. Suitable for Control

The valve's streamlined flow path, which is free of cavities, enhances its throttling and control capabilities. This design allows for excellent flow control, making it an ideal choice for applications requiring precise regulation.
