RETZ Imported Manual Pneumatic Diaphragm Valve

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

RETZ Imported pneumatic diaphragm valves do not require a separate valve stem packing sealing structure. The diaphragm serves as a seal for the valve stem while cutting off the medium. Secondly, the highly flexible diaphragm ensures reliable closure, and can even effectively cut off dirty liquids.

Specification: 1/2"～12"

Temperature: -20～150℃

Pressure: 16bar (232PSI)

Control: Manual+pneumatic, pneumatic normally open, pneumatic normally closed

Main performance of imported pneumatic diaphragm valves

RETZ (Rubber lined, fluorine lined) Pneumatic diaphragm valve is composed of piston type pneumatic actuator and diaphragm valve. The compressed air is used as the power to drive the transmission screw to move the valve core up and down, while pulling the diaphragm up and down to close and open. Feedback signal devices or limit and positioning devices can be attached as required to adapt to automatic control, program control, remote control or flow regulation.

(Single acting normally open type) When the air source enters the cylinder control chamber, the diaphragm is pressed down and the valve passage is closed. When there is no air source pressure in the cylinder control chamber, the diaphragm rises and the valve passage is opened.

(Single acting normally closed type) When the air source enters the cylinder control chamber, open the valve channel. When there is no air source pressure in the cylinder control chamber, the valve channel is closed.

Structural features of imported pneumatic diaphragm valves

1. Excellent corrosion resistance, overcoming harsh working conditions

Imported manual-pneumatic diaphragm valves demonstrate ingenuity in the selection of valve body and diaphragm. The valve body is often made of high-strength materials with certain corrosion resistance, such as stainless steel and cast iron. For highly corrosive environments, some special models undergo special treatment on the inner wall of the valve body or use expensive corrosion-resistant alloys. The diaphragm is made of materials with excellent chemical stability, such as fluororubber and polytetrafluoroethylene (PTFE), which can easily resist the erosion of strong acids and alkalis like sodium hydroxide. For example, in a chemical plant, after using this diaphragm valve to transport high-concentration sulfuric acid, long-term monitoring showed almost no significant signs of corrosion on the valve body and diaphragm, and the equipment operated stably. Compared to previously used ordinary valves, the replacement cycle was significantly extended, effectively reducing production stoppage losses and maintenance costs due to equipment failure.

2. Dual drive modes, flexibly adapting to changing scenarios

RETZ diaphragm valves innovatively combine manual and pneumatic drive modes. In pneumatic drive mode, with compressed air as the power source, the valve responds extremely quickly, enabling instant opening or closing actions and precise control of fluid flow. In automated production lines, they work seamlessly with various sensors and control systems, efficiently regulating flow according to preset programs and real-time monitoring data, meeting the demands of large-scale industrial production for fast and precise control. In the event of emergencies, such as air source failure or control system malfunction, the manual drive mode serves as a reliable backup. Operators can easily open or close the valve through convenient handwheel operation, ensuring that the production process can continue to operate under special circumstances, buying valuable time for troubleshooting and repair, greatly enhancing system reliability and emergency response capabilities.

3. Excellent sealing performance, eliminating leakage

Superior sealing performance is another highlight of imported manual-pneumatic diaphragm valves. Their sealing strength is sufficient to eliminate any leakage, safeguarding the production process. The sealing structure, like a masterpiece of craftsmanship, features a soft and elastic diaphragm that, in the silent closed state, intimately contacts the valve seat, forming a rock-solid sealing barrier that cuts off fluid leakage at the source. Such excellent sealing technology is particularly important in industries with stringent hygiene and safety requirements, such as pharmaceuticals and food and beverage. For example, in the sterile drug production workshop of a well-known pharmaceutical company, after introducing this imported manual-pneumatic diaphragm valve, the problem of drug contamination caused by valve leakage was eradicated, product qualification rates significantly increased, and material losses and economic losses due to contamination were greatly reduced, laying a solid foundation for the company to build an excellent brand image.

4. Easy maintenance, reduced downtime, and doubled efficiency

In terms of maintenance, RETZ imported manual-pneumatic diaphragm valves also demonstrate exceptional convenience. Their structural design is simple and intuitive, consisting of only three parts: the valve body, diaphragm, and drive mechanism, with a minimal number of components, making disassembly and assembly as easy as pie. When the diaphragm needs replacement due to wear or damage, no complicated tools or professional technicians are required; ordinary operators can quickly complete the operation, significantly reducing equipment downtime for maintenance. According to actual usage data, compared to similar traditional valves, the maintenance time for this diaphragm valve is reduced by about 50%, effectively improving equipment utilization and production efficiency, making enterprise production operations smoother and more efficient.

Conclusion

From the stringent challenges of modern industrial fluid control to the technical shortcomings that traditional valves struggle to overcome, RETZ imported manual-pneumatic diaphragm valves, with their dual drive modes as the core and their excellent performance in corrosion resistance, high precision, and easy maintenance as the blade, precisely break through industry development barriers. Whether it is a modern production line pursuing ultimate efficiency or special working conditions with strict safety and environmental requirements, it can become a reliable partner for enterprises to enhance competitiveness with its stable and reliable performance.
