SP SPEEDIVALVE MANUAL OPERATION
ISOLATION VALVES - NW FLANGES
• Easy to operate with visual indication of valve open (SP10K to SP25K)
• Leak tight to better than 10-6 mbar l s-1 / 8 x 10-7 Torr l s-1
• Diaphragm completely isolates mechanism from vacuum system
• Extremely rugged and ‘dirty’ system tolerant
• Will withstand 9 bar overpressure (SP10K to SP40K, with Co-Seal)
BOC Edwards SP Speedivalves are diaphragm sealed in-line, isolation valves available in nominal bore sizes of 10, 16, 25 and 40 mm. They are all similar in construction and consist essentially of a flexible elastomer diaphragm which is sealed onto a lightly polished seat by a screw thread mechanism.

BOC Edwards SP Speedivalves are diaphragm sealed in-line, isolation valves available in nominal bore sizes of 10, 16, 25 and 40 mm. They are all similar in construction and consist essentially of a flexible elastomer diaphragm which is sealed onto a lightly polished seat by a screw thread mechanism.
The mechanism is isolated from the system by the diaphragm resulting in an extremely rugged and ‘dirty’ system tolerant valve. The valve body is made from aluminum and the complete valve is leak tight to better than 10-6 mbar l s-1 / 8 x 10-7 Torr l s-1 at 1 bar differential. Diaphragms are available in nitrile and fluoroelastomer.
The valves terminate in NW flanges and the SP10K, SP16K and SP25K valves can be pipeline supported or panel mounted. These valves have indicators to show the ‘open’ position. The SP40K is suitable for pipeline mounting only.

SP MANUAL OPERATION ISOLATION
VALVES - NPT AND BSP
The Speedivalve range of isolation valves has been extended to include NPT and BSP variants.
• Leak tight to better than 10-6 mbar l s-1 / 8 x 10 7 Torr l s-1
• Diaphragm completely isolates mechanism from vacuum system
• Extremely rugged and ‘dirty’ system tolerant
• Will withstand 9 bar overpressure (with Co Seal) |
The valve body is made from aluminum and the complete valve is leak tight to better than 10-6 mbar l s-1 / 8 x 10-7 Torr l s-1 at 1 bar differential. Diaphragms are available in nitrile and fluoroelastomer. The SP25T can be both pipeline supported or panel mounted.
The SP40T is suitable for pipeline
mounting only.

IBV SERIES VACUUM BALL VALVES
Ball valves are popular in applications where fast action and full bore pumping are needed. The new BOC Edwards IBV series valves combine these practical everyday features plus ease of use and economy in a high specification design. Manufactured in 316L stainless steel with PTFE seats they deliver robust performance in a wide variety of vacuum duties.
The precision engineered ball and PTFE cups contribute to reliable flow control in a high quality construction. This makes them ideal for applications spanning simple vacuum pump isolation to vacuum control in a production, OEM, or industrial laboratory environment. ‘O’ ring sealed NW flanged
models, used with the unique BOC Edwards |
Co-Seal, are rated for pressure duties up to
7 bar absolute. Threaded versions are also available for easy connection into rough vacuum applications.
Benefits
• Low capital cost
• Convenient NW16, 25, 40, 50 sizes
• Optional BSP threaded versions
• Easy to use manual operation
• High conductance full bore pumping
• Rugged design for dirty system use
• Corrosion resistant construction
• Leak tight to better than 1 x 10-6 mbar I s-1 / 8 x 10-7 Torr l s-1
• Wide operating range 10-6 mbar to 7 bar / 8 x 10-7 to 5250 Torr (102 psi)

PVMK MANUAL OPERATION ISOLATION
VALVES
The PVMKA (aluminum body) and PVMKS (stainless steel body) are quick acting, lever operated valves. The lever, connected to a self-lubricating plastic cam-piston, actuates the valve stem and valve plate through PTFE bearings. The valve plate ‘O’ ring groove is vented to prevent gas bursts. |
The valves are designed to operate down to 10- 9 mbar / 8 x 10-10 Torr and up to a pressure of 2100 mbar / 1575 Torr (30 psi).
• Right angle and in-line versions available
• Bellows sealed grease free vacuum
• Aluminum or stainless steel options
