Fluid Power: VALVES & CYLINDERS

• Permits multiple flow patterns
• Handles highly corrosive liquids

Ball valve

Rated for full vacuum service, this cross port ball valve's 3-way design permits multiple flow patterns because of the crossed flow corridors within the ball. It is available in sizes of 1/2- to 2-in., and is manufactured from PVC, CPVC, PP or PVDF, making it well-suited for handling highly corrosive liquids in a variety of industries. Its design achieves four flow patterns through three ports using one valve, which permits flow from common port to left or right ports to "off" position. To accomplish this in past would would have required two different valve body styles and two different ball configurations. Available with electric or pneumatic actuators, the valve has "L" port as standard and Tee Double L porting optional. Asahi/America Inc, Malden, MA. Free info--Circle 530.

NFPA cylinder. These interchangeable cylinders are designed specifically to offer a clean, smooth profile. The aluminum barrel of the DM2 series eliminates the need for tie-rods. They are highly suited for clean environments such as food, drug and processing applications. Mead Fluid Dynamics, Chicago, IL. Free info--Circle 535. http://www.OneRS.net/107df-535

Control valve. This co-ax control valve for flow, pressure and bypass relief applications allows infinite step-less pressure regulation, with actuation speeds as fast as 30 milliseconds. As a result, it can meet the most demanding pressure flow requirements, often replacing multiple valves and regulators. The valve can last up to 10 times longer than others, even when controlling difficult media flow applications. springer co-ax inc, Penndel, PA. Free info--Circle 536. http://www.OneRS.net/107df-536

Double-acting cylinder. The DNA series pneumatic cylinder goes beyond NFPA standards, as pertains to pneumatic cylinder mounting, bore and rod sizes, accessory dimensions and compressed air fitting port sizes. It employs the latest in aluminum profile extrusion technology. Festo Corp, Hauppauge, NY. Free info--Circle 537. http://www.OneRS.net/107df-537

Poly ball valve. This full-port 4-in. ball valve is designed for industrial, commercial and agricultural applications. Pressure rated at 100 PSI at 70°F, it uses precision-molded glass-reinforced polypropylene, and features an 8-bolt assembly and a self-aligning ball for full flow. Bee Valve Inc, Elyria, OH.
