RETZ Imported Pneumatic Y-Type Diaphragm Valve

Brand: RETZ/ We have been committed to continuous innovation in the field of fluid control since 2005...

PVC plastic V-type diaphragm valves use water pressure to directly open and close the valve through the sealing diaphragm. When pressure is applied to the upper chamber of the diaphragm, the diaphragm cuts off the water inlet and closes the valve; when the control chamber is depressurized, the water inlet automatically pushes the diaphragm open to open the valve.

Specification: 1-1/2" to 6" flange connection

Applicable Temperature: ≤50℃

Pressure: 8bar (116PSI)

Material: PVC-U

"Not all diaphragm valves are called 'Y-type valves'—RETZ's design allows viscous fluids to flow as smoothly as water!"

RETZ imported Y-type diaphragm valves feature a dual upper and lower control chamber design, controlling water flow independently from the fluid chamber, making valve control more flexible, reliable, and durable. They are acid and alkali resistant, corrosion resistant, impact resistant, and made of reinforced plastic products with enhanced heat resistance.

If you have any requirements, such as "I want this type of diaphragm valve!" or "I want to use it for this fluid!", please feel free to tell RETZ (Ruici).

Performance characteristics

The closing and opening of the diaphragm valve are achieved by pressure from the pipeline acting on the reinforced rubber diaphragm.

When the pressure medium enters the valve control chamber, the diaphragm is pressed down, closing the valve passage. When the control chamber pressure is released to the atmosphere or downstream pipeline, the diaphragm rises, and the valve passage opens.

The valve has no valve stem, sealing gasket, or directional seat. The only moving part in the passage is the diaphragm, so there is no risk of corrosion or seizing, ensuring higher stability.

1. The imported Y-type diaphragm valve adopts a dual upper and lower control chamber design, controlling water flow independently from the fluid chamber, making valve control more flexible, reliable, and durable, completely eliminating potential issues of poor switching or leakage found in single-chamber control valves.

2. The valve body and bonnet are made of glass fiber-reinforced NORYL material, providing high strength, long service life, and corrosion resistance.

3. The specially treated and formed reinforced rubber diaphragm has a long service life and high fatigue resistance.

4. The Y-shaped fluid channel design reduces pressure loss in the valve and increases water flow capacity.

5. Normally open and normally closed types can be easily and flexibly converted.

6. Additional functions such as spring-assisted opening (closing), flow restriction, or switch indication can be added.

7. There is greater diversity in the choice of pressure sources, as it can be hydraulic or pneumatic.

【Core Selling Points】—Imported Quality · Precise Flow Control · Long-Term Stability
1. Imported brands: Bermad (Israel), RETZ (USA), GE (USA), using European precision manufacturing processes. Core components (such as elastic diaphragms and valve bodies) undergo leak-proof testing to ensure zero leakage performance under high pressure and corrosive media, with a lifespan more than 3 times longer than domestic standard parts.
2. Y-type flow channel design
Low flow resistance structure reduces pressure loss by up to 40%, especially suitable for high-viscosity fluids (such as slurries and colloids) and media containing particles, avoiding sedimentation and clogging, and reducing maintenance costs by 50%.
3. Pneumatic rapid response system
Equipped with high-performance double-acting/single-acting cylinders (optional), opening and closing time <1 second, supports 47Bar air source pressure, and meets the high-frequency switching needs of automated production lines (≥500,000 cycle tests).
4. Super corrosion-resistant combination
Diaphragm options include PTFE+EPDM double-layer composite material (acid and alkali resistant, pH 1-14), valve body made of 316L stainless steel with fluorine lining, suitable for high-risk media scenarios such as chemical and electroplating industries, with FDA food-grade certification (optional).
5. Smart integrated options
Supports the addition of position sensors and PROFIBUS communication modules for real-time feedback of valve status, seamless integration with PLC systems, and meeting the needs of Industry 4.0 smart factories.
