MULTIPLE OPTIONS AND HIGHLY ADAPTABLE DESIGN FEATURES ENABLE SOLENOID-OPERATED
TEFLON ISOLATION VALVES TO EXCEL IN PERFORMANCE, LONG-LIFE RELIABILITY,
AND LOW-COST OPERATING EFFICIENCY |
|
Reliable, continuous duty 2-way and 3-way Teflon isolation valves designed and manufactured by Bio-Chem Valve Inc. feature a long-life, all-Teflon flow path with a choice of PTFE, PEEK, PPS or TEFZEL body to increase performance, reduce cost, and optimize compatibility with aggressive chemicals or high purity fluids. |
|
|
Manufacturers of analytical, diagnostic or environmental instruments employing aggressive chemicals or high purity fluids can select from a wide variety of standard 2-way or 3-way solenoid-operated Teflon isolation valves that are designed and manufactured by Bio-Chem Valves to provide a fast, reliable response in order to meet continuous duty performance at low power levels. Bio-Chem Valve
has designed its standard line of solenoid-operated Teflon isolation valves with an inert, all-Teflon flow path and a choice of other engineered resins including PEEK, PPS, and TEFZEL for the body material and PFA or Kalrez for the seal in order to provide the best value and highest level of compatibility with a wide range of chemicals. Flow path, flow rates and pressure can be customized to suit the application with a uniquely
reliable diaphragm seating element. Valves operate on vacuum to 30 psi in the 2-way normally closed, or 2-way normally open construction, and vacuum to 60 psi in the 3-way multi-purpose valve. Higher pressures are available for special applications |
PINCH VALVE CREATES AN OPEN AND SHUT CASE(EVEN UNDER
VACUUM)FOR RELIABILITY
AND ECONOMY IN HANDLING AGGRESSIVE, PARTICULATE-LADEN LIQUIDS |
Small pinch valves designed and manufactured by Bio-Chem Valve Inc., feature reliability and economy in purging aggressive, particulate-laden liquids from instrumentation and analytical equipment waste lines. |
|
| OEMs seeking to improve reliability and reduce costs in the purging of waste lines containing aggressive, particulate-laden solvents, corrosives, reagents, or other liquids can choose from a range of wide aperture, non-sticking pinch valves designed and manufactured by Bio-Chem. The unusually durable, long-life, non-sticking silicone tubing has been developed in a
proprietary process and may extend the normal preventive maintenance cycle to approach the life of the machine. Bio-Chem pinch valves feature inertness similar to an isolation valve with a straighter, no-clog flow path at less cost. Valves are available in normally closed or normally open position, or in a 3-way configuration for fluid switching. Bio-Chem pinch valves accommodate tubing from .010'' to
.875'' ID. |
HIGHLY EFFICIENT, SPACE-SAVING COLLAR-MOUNT SOLENOID PUMPS AND VALVES FIT
INTO THE SMALLEST MANIFOLD SPACES |
New manifold mountable miniature inert solenoid valves from Bio-Chem Valve Inc. feature a smaller, collar-mount design for efficient , space-saving manifold mounting. |
|
 | Based upon a design that has been in use for the past 20 years, the collar-mount design delivers additional functional advantages. The locked-in threaded mounting collar is hand tightened into the manifold port to ensure an even load on the gasket seal for pressures up to 100 PSI. By positioning the pump or valve closer to the point of
fluid introduction, the collar-mount manifold design minimizes internal volume. For optimum fluid compatibility, these manifold mounted solenoid valves can be customized in a choice of PEEK, PPS, Ultem, acrylic, Chemraz, EPDM, Viton, or Teflon.
Alternative materials, customized design modifications, and stand-alone units are available. Multiple valve sizes can achieve flows from 10 mL/min. to 2 L/min. |
Recognizing an industry demand for smaller, more reliable components for fluid handling equipment, Bio-Chem Valve Inc. has introduced a new line of manifold mountable inert solenoid pumps and valves, with a footprint as small as 0.5'' for space-saving mounting. A highly efficient threaded collar design is employed to secure the valve or pump to the manifold. |
HIGH-PRESSURE MINIATURE ISOLATION VALVES, CUSTOMIZED FROM STANDARD FIELD-TESTED VALVE DESIGNS, MEET OEM'S NEED FOR CRITICAL FLOW CONTROL APPLICATIONS UP TO 550 PSI |
The miniature high-pressure inert isolation valve from Bio-Chem
Valve, Inc. can control critical flow applications up to 550 psi. |
|
| These high-pressure isolation valves feature full corrosion resistance, high cycle life, low power requirements, and fast response times. Inert materials of construction include PEEK, PPS, and Teflon. Quick turnaround is offered for custom modifications. Customizable options
include: port configuration and orientation; voltage; materials of construction; electrical power; and assembly mounting onto manifolds for controlling multiple flow lines. Bio-Chem high-pressure valves can be used to replace more expensive pressure regulator systems or pressure feedback systems where the upper pressure limit needs to be controlled. Applications for high pressure valves include analytical
instrumentation; automatic, programmable pressurized liquid dispensing systems; low viscosity injection molding; and other operations in which low volume high pressure dispensing, safety relief action, or cost saving replacement is desired. |
High-pressure miniature inert isolation valves are customized by Bio-ChemValve, Inc. from a proven design with a
15-year operational heritage. These valves provide the same reliable performance and corrosion resistance in high-pressure applications (up to 550 psi) as Bio-Chem's lower pressure valves. |
SELF-PRIMING MINIATURE FLUID DISPENSING MICRO PUMP PROVIDES RELIABLE, COST-EFFICIENT, LOW-VOLUME DELIVERY OF HIGH PURITY OR AGGRESSIVE
FLUIDS |
New miniature self-priming micro pump, designed and manufactured by Bio-Chem Valve Inc., meets OEM specifications for use in laboratory equipment and instrumentation to assure accurate, repeatable, precision-controlled micro dispensing of high purity or aggressive fluids. |
|
| A new miniature self-priming 5 µL micro pump designed and manufactured by Bio-Chem Valve Inc., provides OEM designers and manufacturers of scientific and electronic instrumentation with compact, reliable, and economical components for handling programmed, precision-controlled micro dispensing of high purity or aggressive fluids. The fixed displacement diaphragm pump
can be factory set to handle discrete fixed output flows in volumes from 5uL to 8µL per solenoid actuation to provide an inert fluid path for precise, repeatable dispensing. The robust Bio-Chem Valve miniature pump, measuring 1-7/8'' high and 3/4'' in diameter, provides a discrete dispense to replace pump and valve combinations, or a continuous pulsating flow to replace maintenance-intensive
peristaltic pumps with reliable, low-maintenance, long-life performance. |
LIGHTWEIGHT, SPACE-SAVING MICRO-MINIATURE VALVE CREATES A
DISTINCT MARKETING ADVANTAGE FOR AUTOMATED LIQUID HANDLING EQUIPMENT |
New micro-miniature solenoid-operated inert isolation valves from Bio-Chem ValveInc. provide high purity flow control in a smaller, lightweight packageand are available in three innovative body designs: side-ported, bottom-ported,or manifold mountable. |
|
| The lighter 12 to 18 gm weight facilitates
use on robotic arms in sample handlers. The valves also feature dual pin electrical connections, low power consumption, low internal volume, and a high cycle life. Applications for the valves include portable liquid handling equipment, repetitive sampling equipment and instruments requiring multiple flow path control within a smaller area. This 2-way normally closed micro-miniature isolation valve comes in 3 body designs.
Two versions incorporate a rectangular body with ¼ -28 flat bottom ports on the bottom or on the side. The manifold version has a screw-in collar for easy assembly and exchange. This design can be combined with an existing manifold or Bio-Chem Valve can custom design an efficient pre-assembled, space-saving module to meet specific flow schematics and eliminate ''spaghetti'' tubing and fittings. The valve
