The EBRO QV pinch valve is designed for on-off control of slurry, powder, and granular media. Its full-bore construction reduces the risk of flow-path blockage. Available in DN 40–DN 200 with EN 1092 PN 10 flange connections, a maximum operating pressure of 5 bar, and natural rubber, EPDM, or FPM diaphragm options. With a solenoid valve installed, electro-pneumatic actuation supports automated solids-laden wastewater and similar pipeline systems.

Application scenarios
Wastewater Treatment Pipelines Containing Sludge or Solids
Used for on-off control in wastewater treatment pipelines conveying sludge or solid impurities. The full-bore design is suitable for these media, with natural rubber, EPDM, or FPM diaphragms selectable according to service conditions.
Pipelines for Powder and Granular Media
Used for on-off control in pipelines conveying powder or granular media. The full-bore design is particularly suitable for such media and can reduce the risk of flow passage blockage inside the valve.
Automated On-Off Control for Pipelines Handling Solids-Containing Media
Used in wastewater or slurry pipelines containing solids that require automated on-off control. Electro-pneumatic control can be achieved by installing a solenoid valve.
Selection points
Full-Bore Design for Particle-Containing Media
The valve features a full-bore design and is particularly suitable for media containing sludge, powder, and particles.
5 bar Operating Pressure and 2 bar Control Pressure Differential
The valve has a maximum operating pressure of 5 bar and a differential pressure of 2 bar between control air pressure and operating pressure. Pneumatic actuation with electrical control can be achieved by installing a solenoid valve.
Multiple Diaphragm Materials Available
Natural rubber, EPDM, and FPM diaphragms are available. Material selection can be matched to the medium and temperature requirements.
Installation in Any Position
The valve can be installed in any position, making it suitable for applications where the installation orientation must follow the on-site piping layout.
FAQ
What media are suitable for the EBRO QV pinch valve?
The QV pinch valve has a full-bore design and is suitable for media containing sludge, powder, or particles, helping reduce the risk of material retention and blockage inside the valve. Compatibility between the medium and diaphragm material should be confirmed based on actual operating conditions.
How should the nominal diameter and flange connection be selected for the QV pinch valve?
QV is available in nominal diameters from DN 40 to DN 200. Its connection flanges comply with EN 1092 PN 10, and the flange sealing face is EN 1092 Form C/E. Select the valve to match the pipeline diameter, flange standard, sealing face type, and on-site piping conditions.
What are the pressure, temperature, and control air pressure requirements for the QV pinch valve?
The valve has a maximum operating pressure of 5 bar and an operating temperature range of -20°C to +140°C. Actual temperature capability depends on pressure and the medium. The differential pressure between control air pressure and operating pressure is 2 bar, meaning the control air pressure must be 2 bar higher than the operating pressure.
Can the QV pinch valve be automatically controlled?
Yes. A solenoid valve can be installed on the QV to provide electro-pneumatic control, making it suitable for applications requiring pneumatic opening and closing controlled by electrical signals.
What diaphragm materials are available for the QV pinch valve, and are there installation orientation restrictions?
QV is available with natural rubber, EPDM (ethylene propylene diene monomer rubber), or FPM (fluoroelastomer) diaphragms. The valve body is aluminum alloy, and the flanges can be supplied with Rilsan coating or Rubber coating. The valve can be installed in any position.
