Pure-Flo 970 Stainless Steel Manual Diaphragm Valve
The Pure-Flo 970 is a compact manual weir diaphragm valve with a 316 stainless steel bonnet, offered in the smaller line sizes common to pharmaceutical and bioprocessing installations. It is autoclavable and built to stand up to standard washdown protocols.
Product Benefits
- Stainless bonnet, PES handwheel: The stainless bonnet pairs with an FDA-compliant PES handwheel for a light, corrosion-resistant package.
- Washdown resistance: The combination resists alcohol, chloride and most caustic washdowns.
- Quick to service: Easy assembly and disassembly simplify maintenance and diaphragm change-out.
- Position at a glance: A rising handwheel and visual position indicator let operators read valve position immediately.
- Diaphragm protected: An adjustable travel stop and an O-ring splash seal are standard, keeping the diaphragm safe from over-compression.
Where It's Used
- Pharma and bioprocessing: It serves pharmaceutical and bioprocessing plants.
- Compact hygienic lines: Its place is on small hygienic process and utility lines.
- Small footprint: It is chosen where an autoclavable valve with stainless topworks is wanted without taking up much room.
Good to Know
- 316L wetted path: The wetted path is a 316L stainless body with PTFE or elastomer diaphragm options, backed by a stainless steel stem and compressor.
- End connections: Hygienic clamp, tubing and international end connections are available.
- Weir design benefits: As a weir-type Pure-Flo valve, its diaphragm isolates the mechanism from the product and the design supports in-line maintenance.
- Small-size specialist: It covers the smaller end of the size range, while larger lines are served by other bonnets in the family.
