Air operated Pinch Valves

Product catalog summary
Overview: This document provides technical specifications and details for AKO Armaturen's pinch valves, designed for handling abrasive, corrosive, and fibrous products such as granules, powders, and slurries. The document outlines various connection options, valve functions, construction materials, and applicable industrial areas.
Connection Options:
  • Flange Connection
  • Internal Thread Connection
  • Tri-Clamp
  • Weld-on Ends
  • Threaded Spigot (RJT Connection)
  • Semi-Silo Trailer Connection
  • Threaded Hose Nozzles
Valve Advantages:
  • Optimum tightness
  • Free passage
  • Low resistance
  • Easy maintenance
  • Low air consumption
  • Low weight
  • No plugging
Valve Function: The pinch valve operates by using air or fluid with a minimum differential pressure of 2 bar to close the valve body. The specially designed sleeve ensures a complete seal. The maximum operating pressure ranges from 2 to 6 bar, depending on the valve diameter.
Construction and Materials: The valves are available in various materials and sleeve qualities, allowing for a wide range of applications. Optional control systems enhance safety and functionality, especially in vacuum systems and hazardous areas (ATEX directive 94/9/EG compliance).
Industrial Applications:
  • Pneumatic conveying systems
  • Cement/silo industry
  • Pigment and granulate processing
  • Ceramic, glass, and plastic industries
  • Sewage water treatment
  • Pharmaceutical and food industries
  • Vacuum toilet systems
  • Dosing and weighing systems
  • Powder coating systems
  • Vacuum conveying systems
Technical Specifications: Detailed tables provide dimensions and pressure ratings for various series and connection types, including flange and internal thread types. The document also lists phased-out models and their replacements.
Sleeve Materials: Various sleeve materials are available, including natural rubber, EPDM, NBR, and silicone, with options for food-grade and electrically conductive sleeves.
Accessories: A range of accessories is available to complement the pinch valves, including solenoid valves, pressure regulators, and safety arrangements. Detailed information is available in the separate "Valve Accessories" data sheet.
