Control Valves - (1646 companies)Control valves are power-operated devices used to automatically modify fluid flow or rate pressure in a process system. The terms 'control valve' and 'throttling valve' are often used interchangeably but there is a distinction...Valve TypeActuationCryogenic Valves -
Chillers (industrial) - (540 companies)Industrial chillers cool water using refrigeration cycles to provide a constant stream of coolant for manufacturing and laboratory processes. Industrial chillers provide a constant stream of coolant for manufacturing and laboratory processes... -
Gas Compressors and Gas Compressor Systems - (323 companies)...through the system by the motion of rotating lobes, screws, or vanes. Dynamic compressors, including axial and centrifugal systems, are another type of compressor. Gas compressors use a variety of technologies to compress gas. Axial: Multiple-blade... -
HVAC Chillers - (202 companies)Heating, ventilation and air conditioning (HVAC) chillers are refrigeration systems that provide cooling for industrial and commercial applications. They use water, oils or other fluids as refrigerants. HVAC chillers include a compressor, condenser... -
Screws - (1402 companies)A screw is a wide-encompassing type of hardware fastener that attributes its mechanical capabilities to the helical groove that extends around the circumference of the device's shank. These threads provide the friction and traction that serves... -
Ball Slides - (100 companies)Ball slides are simple linear motion devices that provide smooth linear motion, accurately controlled by the rotation of the drive mechanism. Ball slides are sometimes referred to as ball and rod bearing assemblies, or ball bearing slides. Ball...
-
Gate Valves - (1164 companies)Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow. Gate valves (also known as knife valves or slide valves) are linear motion valves in which a flat closure element...
-
Lead Screws and ACME Screws - (68 companies)...in zero-backlash arrangements. ACME screws are square-topped and have a specific thread-geometry. By directly contacting the nut, ACME screws provide linear motion through direct sliding friction between the nut and the screw. For both lead screws and ACME...

Beswick Engineering Co., Inc.
Slide Sleeve Valve, 10-32 Thread, Venting Beswick's miniature MSV slide sleeve valve provides an efficient in-line three-way valve. When the sleeve is moved to the "ON " position, fluid is allowed to pass through the valve. When the sleeve is moved to the "OFF " position, the outlet is exhausted to the atmosphere and fluid is prevented from exiting the inlet port. The valve can be attached directly on a device to be isolated and does not require mounting. The maximum pressure rating of the valve is 200 psig and the flow restriction... (read more) -
