This is an MDC stainless steel, bellows-sealed, pneumatically actuated high vacuum valve with 1-1/3" Conflat type flanges and mechanical position indicator switches.

Our price: $300  -  we may also have a second one like this on hand.

This valve did not come to us in sealed factory packaging, and we do not know its history - but if it has been used, then that use was very gentle indeed! It appears to be clean inside and out, and in excellent condition both cosmetically and functionally. The knife edge sealing surfaces are in excellent condition. The valve checks out leak-free (both across the poppet and across the bonnet seal, body, bellows, etc.) as checked by a helium mass spec. leak detector.
  • stainless steel valve
  • 1-1/3" (mini) Conflat-type flanges
  • bellows-sealed actuation (air to open, spring to close)
  • mechanical position indicator switches (a rather expensive option from MDC)
