Product Listing

Aluminum Gate Valves Specifications


Features
  • MDC’s NEW Line of aluminum gate valves feature a robust design and cost effective solution for a multitude of applications.
  • Aluminum gate valves are available in standard sizes ranging from 1-1/2” (40mm) through 6” (160mm) ID with manual actuation and 1-1/2” (40mm) through 12” (320mm) with pneumatic actuation.
  • Standard flange configurations include ISO KF & LF with options for ASA and JIS on request.
  • The aluminum body is precision machined from a solid billet of high strength 6061-T6 aluminum. This eliminates pinholes and virtual leaks that can appear in cast or welded aluminum valves.
  • Dual quad ring shaft seals are used to improve seal life and leak integrity while increasing system uptime to as many as 400k cycles.
  • High performance PEEK components help reduce friction and lower particle levels.
  • A large diameter direct drive shaft is utilized to help reduce vibration during actuation.
  • Split body design optimizes on tool maintenance and reduces downtime.
Options
  • Solenoid: 24 VDC, 110 VAC, 240 VAC
  • Roughing Ports
  • Alternative sealing material
  • Heater jackets
  • Optional flange options: including ASA and JIS
