Swagelok Company is a $2 billion privately held developer of fluid system products, assemblies, and services for the oil and gas, chemical and petrochemical, [2] semiconductor, and transportation industries.
Needle Shut-off Nozzle type HP - pneumatic or hydraulic actuation The melt flow is shut off via a melt channel-axis positioned needle moving back and forth according to actuation. This nozzle type shuts off the melt stream directly at the nozzle orifice-mold interface which prevents drooling.
Fred Lennon was born in Providence, Rhode Island, to Patrick and Catherine Lennon, as the youngest of their nine children. [2] By the age of 42, he was living with his wife in an apartment in Cleveland, Ohio, when he borrowed US $500 from his wife's uncle to buy The Crawford Fitting Company later to be renamed Swagelok Company.
An instrument needle valve uses a tapered pin to gradually open a space for fine control of flow. The flow can be controlled and regulated with the use of a spindle. A needle valve has a relatively small orifice with a long, tapered seat, and a needle-shaped plunger on the end of a screw, which exactly fits the seat.
Globe valve. A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. [1] Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.
Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open. A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is ...
Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, a flexible diaphragm, and a "weir or saddle" or seat upon which the diaphragm closes the valve. The valve body may be constructed from plastic , metal or other materials depending on the intended use.
Fluid in the hollow core is then forced to go through an orifice at the top, a one way check valve at the bottom of the hollow core prevents the fluid from escaping through the bottom. After the fluid is expelled, the core completes its upward movement and closes an air gap in the core, which in turn increases its electromagnetic field strength.
