Pneumatic actuators

CRHD linear actuators for hygienic environments utilize the same stainless-steel design that allows the device to function in aggressive environments where acids, bases, and powerful cleansers are used. To function in sterile environments, the actuators incorporate a cylindrical shape and integral mounting component on the rear cap. Since there are no corners or debris collection points on the exterior surface, fluids and matter drain off during cleaning.

Valves

The A45 valves, available with orifices of 2, 4, and 6 mm, are used on machines and systems to control liquids and gases. The valve line is ideal for applications where 100% tight shutoff is required, such as pressure decay testing machines. They offer all-stainless-steel construction, with working pressures to 1,950 psi. springer co-ax inc., Box 7204, Penndel, PA 19047; FAX (888) 757-4060; www. coaxvalves.com.

Pumps

SV600 Series of solenoid-operated dispensing pumps employs an O-ring pumping system, which seals the piston while allowing the pump chamber to refill. The piston is retracted when the solenoid is energized, allowing liquid to enter the volume above the pump O-ring. A return spring pushes the piston back down when the coil is de-energized. The user can adjust volume output per stroke, and can control flow rate per minute.

Diaphragm valves

A patented radial-diaphragm-valve design eliminates entrapment areas and allows for easy drainage. It can be manufactured in a wide range of configurations to include multiple valves and multiple ports. This versatility can result in a more compact flow stream, built with fewer valves, less piping, and fewer connections. Designed and tested for durability and long cycle life, particularly in steaming applications, every diaphragm is machined from virgin PTFE.

Pressure sensors

Miniature amplified pressure sensor utilizes a monolithic design based on piezoresistive technology. The components that provide temperature compensation and output amplification are located on the silicon piezoresistive chip. It is constructed of glass, solder, and silicon with a stainless-steel port. The 6-pin DIP package is designed for printed circuit board mounting.
