These industrial-grade solenoid coaxial valves replace conventional motor-driven valves
for the control of liquids, gases, vacuum, and a variety of media with pasty, gelatinous,
aggressive or abrasive properties. CO-AX coaxial valves incorporate a process valve and an
actuator in a single integral unit that has only one moving part. The direct-acting units
are pressure balanced and require no minimum pressure drop to operate, enabling function
from zero to full pressure differential, as well as bi-directional flow. Construction
materials are available to suit virtually all applications, with sizes from 1mm to 3 in.
Depending on size, both 2- and 3-way versions are rated from vacuum to 7,500 psi. Options
include threaded or flanged connections and explosion-proof designs. Springer Co-Ax

Single valve manifolds. Two in-line single valve manifolds
have been added to the EV/ET Valve line. The 15491-1 Valve Pilot Adapter has 1/8 NPT
fittings to install between the valve and cylinder, with the air supply attached to a
10-32 threaded inlet port. The 15491-2 In-Line Manifold is configured to permit the
attachment of a valve to a "T"-fitting in the air supply line with the 1/8 NPT
fitting, with an outlet port of 10-32 size. Clippard Instrument Laboratory Inc, Cincinnati,
OH. 513-521-4261.
Rotary vane pump. For use in liquid media applications, the
F-Series rotary vane pumps have precise internal tolerances and features that ensure the
lowest possible operating noise. No rubber parts reduces compatibility problems. The
design also prevents leakage in the event of pump failure. The series has a maximum
capacity of 2 lpm and pressure ranges up to 2 bar. Hydraulic parameters can be adjusted to
accommodate custom requirements for viscosity, speed and pump gap. ASF Thomas, Norcross,

Shutoff valves. The G-Series valves, available in shutoff,
needle or check types, have been engineered for a wide range of applications. A choice of
8 different seal materials should suit most applications, for temperature ranges of -65°
to 400°F, and the valves are rated for up to 6,000 psi for liquid or gas. Body
configuration is either angle or inline, and there are 12 end connection options. Air
actuation is an option on all G-Series. CPV Manufacturing Inc, Philadelphia,

Upgraded pumps. Several aspects of this company's K series of
pumps have been upgraded. Maximum pressure capabilities have been increased from 2500 to
3000 psi continuous. New features include a reinforced cover; individually cast,
reinforced gear plates; and an improved sleeve bearing. Models within the series have
displacement ranges from 0.86 to 3.88 in3/rev, flows up to 44.7 gpm, and speeds
up to 300 rpm. Danfoss Fluid Power Inc, Racine, WI. 262-884-7400. http://www.danfoss.com/fluidpower/

Servo-drive peristaltic pump. A panel-mount drive for 313D and
501RL pumpheads has been introduced. The drive consists of a high-torque brushed DC servo
motor, coupled to a zero-backlash gearmotor for ultra-quiet operation. A choice of three
gear ratios allows speeds up to 500 rpm. The pump drive is mounted on a flat aluminum
plate, and the motor is coupled directly to the rotor of the pumphead, saving space.

Hydraulic cylinders. A line of short stroke hydraulic
cylinders are available for space-limited applications where all fluid lines and fittings
are isolated from the work area. Fluid passages are located within the user's structure,
and connect to the cylinders through trepanned ports at the mounting face. Rated for 1500
psi, the cylinder line has nine sizes ranging from 1 1/2- to 2 1/2-in. OD., and strokes in
1/10-in. increments to a maximum of four in. Mack Corp, Flagstaff, AZ.

Thermoplastic ball valve. Manufactured from PVC, CPVC, PP or
PVDF, the Type 21 Ball Valve is offered in sizes of 1/2- to 4-in. Pressure rating for
sizes up to 3 in. is 230 psi, and 150 psi for 4 in. (150 psi for PP, all sizes) at 70°F.
The Type 21 has double O-ring seals on the stem, and is of blowout-proof design. Other
features include Teflon seats with EPDM or Viton; full vacuum rating; seals made from
EPDM, Viton or AFLAS; and a choice of connection designs. Asahi/America Inc, Malden,

Heated valve.
Designed for use in the semiconductor process, the HPS Jalapeņo LoPro valve develops a
minimum internal temperature of 150°C. By heating the valve, condensed byproducts of a
process can exit as a gas. These poppet-style valves, smaller than standard vacuum poppet
units, are available in NW 25, 40 and 50 sizes, in angle and inline configurations. A
built-in thermostat and thermal fuse for the heater are standard. MKS Instruments,

Pressure/vacuum pump. The Micro Air "C" Pump is
available for OEM pressure and vacuum applications. The pump delivers flow rates up to 9.5
lpm, maximum pressure of 14 psig, and maximum vacuum of 19 in. Hg. A long-life version
uses a precision, coreless DC motor for thousands of hours of trouble-free performance.
There is also a lower-cost version equipped with a standard iron-core type DC motor for
intermittent-use applications. Line ports are 1/4-in. diameter OD slide-on fittings. Sensidyne
