Soft tip valves feature a patented Acetal non-rotating soft tip stem (U.S. Patent 6,820,857). Patented body-to-bonnet, metal-to-metal seal significantly increases the pressure range of the valve (U.S. Patent 7,758,014).
200 Series Multiport, Hard Seat Needle Valves
Multiport design for multiple instrument connections that can be bled off for safe removal. Optional bleed plugs further allow pressure to be bled off without disturbing the permanent piping installation. 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability. Blow-out proof stem provides a secondary stem seal in the fully open position.
300 Series Multiport, Soft Seat Needle Valves
Multiport design for multiple instrument connections that can be bled off for safe removal. 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability. Replaceable Acetal seat and straight through porting for bidirectional, high-capacity flow and easy roddable cleaning.
400 Series Standard, Hard Seat Needle Valves
100% helium leak tested to 1 x 10-4 ml/s for performance and reliability. Blow-out proof stem provides a secondary stem seal in the fully open position. FKM o-ring seal and PTFE back-up ring below the stem threads to protect from corrosion and galling; PTFE or Graphite packing optional.
500 Series Standard, Soft Seat Needle Valves
100% helium leak tested to 1 x 10-4 ml/s for performance and reliability. Replaceable Acetal seat and straight through porting for bidirectional, high-capacity flow and easy roddable cleaning. Blow-out proof stem provides a secondary stem seal in the fully open position.
600 Series Block and Bleed, Hard Seat Needle Valves
Block and bleed design allows pressure to be bled off, allowing quick and safe instrument removal. 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability. 0.090" bleed hole located on the bottom is controlled by a 1/4"-20 UNF-2A bleed screw.
700 Series Block and Bleed, Soft Seat Needle Valves
Block and bleed design allows pressure to be bled off, allowing quick and safe instrument removal. 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability. Replaceable Acetal seat and straight through porting for bidirectional, high-capacity flow and easy roddable cleaning. 0.090" bleed hole located on the bottom is controlled by a 1/4"-20 UNF-2A bleed screw.
800/850 Series Bleed, Hard Seat and Soft Tip Needle Valves
Bleed valves relieve process pressures trapped between a shut off valve and the instrument. 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability. Soft tip valves feature a patented Acetal non-rotating soft tip stem (U.S. Patent 6,820,857). Patented body-to-bonnet, metal-to-metal seal significantly increases the pressure range of the valve (U.S. Patent 7,758,014).
2070 Series 2-Valve Block and Bleed, Hard Seat Needle Valves
Block valve isolates the process, and the bleed valve exhausts the media, enabling safe removal of the instrument without disturbing the permanent piping installation. The 1/4" NPT vent plug may be removed to direct media, or for test and calibration. 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability.
2170 Series 2-Valve Block and Bleed, Soft Seat Needle Valves
Block valve isolates the process, and the bleed valve exhausts the media, enabling safe removal of the instrument without disturbing the permanent piping installation. The 1/4" NPT vent plug may be removed to direct media, or for test and calibration. 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability. Replaceable Acetal seat, and straight through porting for bidirectional, high-capacity flow and easy roddable cleaning.
3070 Series 3-Valve Double Block and Bleed, Hard Seat Needle Valves
Block valve isolates the process fluids and redundant bleed valves provide additional safety to exhaust the media for safe instrument removal. The 1/4" NPT vent plug may be removed to direct media, or for test and calibration. 100% helium leak tested to 1 x 10-4 ml/s for performance and reliability.
