This valve is a simply structured regulating valve designed for opening and closing control in low-pressure pipeline systems handling bulk powders and granules. The closing member, referred to as the valve disc or butterfly plate, is a circular disc that rotates around the valve shaft to achieve open and closed positions. It is commonly used in dilute phase pneumatic conveying applications where reliable shut-off and moderate sealing are required.
Simple structure makes it easy to maintain and repair.
Low pressure drop across the valve when fully open.
Compact design requires less installation space compared to other valve types.
Fast operation with 90-degree rotation from fully closed to fully open.
Cost-effective solution for low-pressure powder handling applications.
The valve disc rotates around a central shaft with 90-degree actuation travel. The six-petal disc design provides balanced contact with the valve seal. Available with pneumatic or manual actuation options. Internal surfaces can be finished to food-grade or pharmaceutical-grade standards. Seal materials include silicone, EPDM, FKM, and Buna for various material compatibility requirements.
This six-petal valve is suitable for on-off control of dry powders, granules, and dusty materials in low-pressure pneumatic conveying systems. It is widely used in chemical, food processing, pharmaceutical, and building material industries for applications such as dust collector discharge, bin venting, and gravity flow shut-off.
Do not exceed rated pressure or temperature. Keep sealing surfaces clean before closing. Actuate fully open or fully closed only; avoid throttling. Inspect seals regularly for wear. Disconnect air and power before maintenance.

Q: Can this valve be used for throttling or partial opening control?
A: No. This valve is designed for fully open or fully closed positions only. Partial opening will cause accelerated seal wear and reduce service life significantly.
Q: How do I select the correct seal material for my application?
A: Choose based on material compatibility and temperature. Silicone suits food and pharmaceutical use. EPDM works for water and mild chemicals. FKM resists high heat and oils. Buna handles fuels and petroleum products.
Q: What maintenance is required for the pneumatic actuator version?
A: Check air supply pressure regularly. Inspect hoses and fittings for leaks. Clean or replace the air filter element every three months. Lubricate the actuator cylinder per manufacturer instructions.
