Paladon valves

Paladon PV Bought out by AKO UK

  AKO Pinch Valves are also a lot more light weight because they no longer have heavy cast iron flanges. Instead they now come in aluminium with a choice of bushing material if required, such as mild steel or stainless steel. The rubber sleeves inside the AKO Pinch Valves are also improved with extra walls,…

The Importance of Abrasion Resistant Valves

More and more engineers and plant workers are opting for the Pinch Valve when fitting or replacing abrasion resistant valves. The Pinch Valve is a highly robust type of valve that is extremely reliable, with a very good elasticity. One of the main positive factors of this type of abrasion resistant valve is that it has lightening fast opening/closing times, ensuring a quick shutoff.

pinch valve mechanism

Understanding the Pinch Valve Mechanism

Having the simplest valve design, pinch valves comprise of a flexible elastomer body that obstructs the flow of media through the pinching mechanism of the rubber sleeve, which is the main working element. The rubber sleeve is pinched closed either by the application of fluid pressure or mechanically in the body. It is squeezed at the valve’s mid-section, clamping or pinching its walls together to tightly close the flow path.

low blocking valves

Low Blocking Valves Keep a Free Flow of Product in any Industry

Low blocking valves of the rubber squeeze type (commonly recognised as the Pinch Valve) are extremely good at keeping a free passage with no dead spots or blockages. They are either operated pneumatically using compressed air, or manually with a hand wheel.

Manually operated low blocking valve closed with spring pistons

Both types have a specially constructed rubber sleeve or hose inside the body of the valve, which has a very high resilience and is exceptionally durable. Even when used on aggressive or corrosive media, the sleeves come in different types of rubber so can handle almost every application.

sterile valves

Stainless Steel Sterile Valves are used in Aseptic & Pharmaceutical Applications

Sanitary or sterile valves are one of the best choices for applications where sterility, cleanliness, zero dead volume, and uninterrupted flow are of utmost importance. The rubber tubing inside the sterile valves provides an unobstructed flow path that drastically reduces shear effect and turbulence of the media. This also results in minimal loss in pressure, which further improves the efficiency of the system. The flowing media also stays inside the original supply tube.

low maintenance valve

Low Maintenance Valves are key to Industrial Applications

One of the highlighting features of the pinch valve is that it requires little to no maintenance. This is because the only part that undergoes wear and interacts with the flowing media is the rubber sleeve. The component is made of a highly corrosion and abrasion resistant material, such as rubber, silicone, and several other forms of elastomers, which dramatically increases the wear-life of the sleeve in these maintenance free valves.

valves for cement

Valves for Cement, Concrete and Slurries

The processes in this industry require valves for cement that are highly abrasion and wear resistant, because of the nature of materials used in the manufacturing of cement. Pinch valves are the best valves for cement, as they are embedded with a high quality elastomer sleeve present in its housing. This component allows tight control over the cement flow in the transfer lines, as well as keeps the media from interacting with the rest of the system.
