Dariof FassiniAll perfect. Quality is 4.5 on 5 but quality to price ratio is excellent. -
Jasper MokkinkI have had an great experience ordering from Wolfy! The communication was always quick and clear. Adding parts to your order after you made your payment is also accepted by Wolfy. They are also willing to hold your order for a little bit if you need time to decide what additional parts you would like to add. I ordered compression fittings.

Features of VCR pneumatic diaphragm valve
| Diaphragm sealing | VCR pneumatic diaphragm valves use a flexible diaphragm to create a seal between the valve body and the fluid flow path. This diaphragm can be made of various materials, including Teflon, EPDM, and Viton, to suit different process fluids and temperatures. |
| Pneumatic actuation |
These valves are controlled by a pneumatic actuator, which opens and closes the valve by applying air pressure to the diaphragm. |
| High-purity design | VCR pneumatic diaphragm valves are often used in high-purity applications where contamination must be minimized. They are designed with smooth surfaces, minimal dead space, and easy-to-clean materials. |
| Leak-tight performance | The diaphragm sealing mechanism of VCR pneumatic diaphragm valves provides excellent leak-tight performance, making them suitable for critical applications where even small leaks can be problematic. |
| Modular design | VCR pneumatic diaphragm valves are often designed with a modular construction, which allows for easy replacement of individual components and simplified maintenance. |
| Wide range of sizes | These valves are available in a wide range of sizes, from small-scale laboratory valves to larger industrial valves. |
| Versatile applications | VCR pneumatic diaphragm valves can be used for a variety ofapplications, including in pharmaceuticals, biotechnology, semiconductor manufacturing, food and beverage, and chemical processing. |
| Compatibility with VCR fittings | VCR pneumatic diaphragm valves are designed to be compatible with VCR fittings, which are widely used in high-purity applications for their leak-tight, metal-to-metal sealing. |
| Low maintenance | Due to their simple design and modular construction, VCR pneumatic diaphragm valves require low maintenance and have a long service life. |
