Product description

Manual diaphragm isolation valve with KF25 flange, leak-tight to 10⁻⁶ mbar·l/s, rugged, supports 9 bar overpressure.

  • Diaphragm type: Viton fluoroelastomer diaphragm fully isolates valve mechanism from the vacuum system
  • Valve design: Flexible elastomeric diaphragm sealed onto a polished seat via screw thread
  • Connection: KF25 (NW25) flange compatible with pipeline or panel mounting
  • Leak tightness: Better than 10⁻⁶ mbar·l/s (8 x 10⁻⁷ Torr·l/s)
  • Pressure tolerance: With Co-Seal, withstands up to 9 bar overpressure
  • Operation: Manual with visual indication of valve open position
  • Application: Suitable for rugged and ‘dirty’ vacuum systems due to diaphragm isolation preventing mechanism contamination
  • Additional: Refer to datasheet for detailed specifications and operational guidance

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
