Type 15 Diaphragm Valve

Description

Diaphragm valves offer many combinations of body materials and elastomeric diaphragm materials. The valve design is abrasion-resistant and non-clogging. When the diaphragm, which is connected to the stem of the valve by a compressor, is pulled away from the bottom of the valve body or weir, the path of the fluid has a smooth, streamlined flow. Slurries at low pressure that would normally clog most other valve designs easily pass through a diaphragm valve. The valve has a top-entry design, allowing in-line maintenance; it is suitable for throttling and on/off service in applications ranging from water treatment to chemical abrasion processes. Diaphragm valves are operated manually, electrically, or pneumatically.

Features and Benefits

  • Flanged face-to-face dimensions are equivalent to those of Type G diaphragm valve
  • Rugged body and bonnet are of solid thermoplastic for maximum corrosion resistance
  • Bubble-tight sealing, even in applications such as slurries or suspended particles
  • Weir design for excellent throttling
  • Uniquely designed body and bonnet together with diaphragms of new sealing designs by the state-of-the-art computer aided analysis for superior sealing
  • Bonnet seals to protect internals from corrosive environments
  • Built-in travel stop to prevent diaphragm from being over-tightened
  • Indicator at the top for valve position and prevention of over-tightening
  • PVDF gas barrier, which protects EPDM backing cushion from gas permeation, is standardized for PVDF valves
