The new Pinch Valve from LAD uses various materials such as cast iron, carbon steel, stainless steel, and aluminum alloy. It comes in two structures: closed and bare. Additional components, such as a positioner, solenoid valve, limit switch, air filter, and junction box, can be retrofitted for remote control. The valve body has a flat and aesthetically pleasing appearance and can be painted. It is an ideal substitute for imported valves. The sleeve is handmade using solid-liquid, two-phase rubber as the main material, reinforced with cord fabric, and finally synthesized with natural rubber. It is lined for added durability.
