Fully Closed Body Pinch Valve Ductile Iron Body Handwheel Operation For Sand And Gravel

Fully Closed Body Heavy Duty Ductile Iron Body Slurry Pinch Valve For Sand And Gravel

When comparing to conventional valves such as knife gate sliding valves, butterfly valves, ball valves and so on, the Pinch Valve does not have any additional parts that will need replacing every so often such as rings, seals and packing etc, giving the Pinch Valve a very good total cost of ownership.

Other advantages of the Pinch Valve include:

• Low & easy maintenance
• Low weight
• No clogging or dead spots
• Compact, simple, robust & straight through design
• Very fast opening/closing times
• Less air consumption
• Self cleaning
• Permanent seal with tight shutoff
• Minimal turbulence & friction
• No mechanical parts, and no bearings, seals or packing required.
• Only one replaceable part (elastomer sleeve)

Metallic Valve VS TEKO Sleeve Valve

Metallic Valve: When abrasive particles and metal collide, the collision energy is absorbed into the metal and cause scratch and damage on the metal surfaces

Rubber sleeve: When particles hit the elastomer sleeve, the collision energy is absorbed and released immediately as the particle bounces back. This results in excellent wear resistance and long service time.

TEKO Elastomer Sleeves 

1. Inner Layer: Natural rubber/Synthetic Rubber

The inner layer is the key part of the pinch vale which contacts the medium. It is decided by the working conditions.

2. Cord fabric: to improve the pressure retraining capabilities, make sure that the sleeve work well during operation. Layer quantity depends on the working pressure and vale size.

3, Outer layer: to protect the sleeve from the environmental corrosion, with features of high elasticity, tear-resistance and high fatigue-resistance
