  • Hastelloy C276 wetted parts for use to 12,000 psi
  • “Four-corners” integrated mounting points for consistent 25mm / 1” grid spacing shared by all MV valves & fittings.
  • Several valve models available, including two-stem needle valve.
  • Non-rotating V-type stem for on/off service with increased durability.
  • AL-Bronze seal keeper provides smooth actuation.
  • Bubble-tight valve shutoff for working with gases.
  • Standardized tubing connection requires no special tools.Compatible with Autoclave Speed-Bite™ and BuTech ferrule compression systems (1/8” or 1/16” tubing).
  • Range of O-ring seal materials available: UHMWPE, Viton, Aflas, Chemraz, Buna-N,, etc.). O-ring seal is common size (2-008) and readily available.
  • In-stock for quick delivery & world-wide shipping. Common models of needle valves and fittings are available for quick delivery.
There are several seal material options available for Vindum MV Needle Valves. The most common O-ring materials are listed here:
  • Viton (fluorelastomer or FKM): 0°C-200°C, Elastomer. Excellent for oils & most chemicals. Avoid phosphate esters and ketones. This is the standard O-ring material supplied, unless otherwise requested.
  • Buna-N (NBR/Nitrile elastomer): several grades available. Continuous use to about 110°C, but HBNR compounds available to 150°C. Good for petroleum oils & fluids, water. Not recommended for ketones (MEK, acetone), strong acids >10% concentration), and halogenated or nitro hydrocarbons.
  • UHMW-PE (ultrahigh molecular weight polyethylene – thermoplastic): Self-lubricating (low friction), long-wearing, excellent abrasion & chemical resistance (including petroleum oils, organic alcohols, ketones, and acids). Not recommended for use with highly oxidizing chemicals (eg, bleach) or chlorinated solvents (cause swelling). Maximum operating temperature 82°C.
  • AFLAS (TFE/P or FXM elastomer): Excellent chemical resistance to most acids & bases, amines, petroleum oils & fuels, and steam. Good permeation resistance but not as resilient as Viton. Maximum operating temperature 204°C.
  • Chemraz/Kalrez (FFKM): Excellent chemical, heat, and explosive decompression resistance. Expensive. Maximum operating temperature 249°C (higher in special formulation).
  • Other: Other O-ring materials are available. Please contact Vindum Engineering to discuss.
