Sinclair Collins – A Parker Company
Valves
Sinclair Collins has been setting the standards for control valves used on industrial processes for over 50 years. The diaphragm operated design gives them the ability to be used as steam valves, modulating control valves, two-pressure hydraulic control valves, pressure regulating, and pressure relief valves. These valves are perfect for high pressure service, hot and cold water, air, and inert gas service. You can use their control modules for maintaining and balancing the air pilot signals. They also offer high pressure check valves.

SC2000 Series Process Control Valves
Stainless Steel, 400 PSI
Diaphragm-operated valves provide a simple and effective means of achieving automatic control of fluid media in manufacturing processes. These valves are used extensively to control steam, hot and cold water and vacuum on automatic presses used to cure tires, V-belts and other rubber and plastic products. They are used to control steam in applications where constant temperature must be maintained to keep materials fluid for processing, molding or curing.
The unique design and reliable peformance of the SC2000 Series Process Control Valves make them ideally suited for various process applications. These rugged cylinder-actuated stainless steel valves are designed for a bubble- tight seal. Their slimmer shape enables them to fit into applications where space is a consideration. Additional flexibility is provided by the choice of inline or flange mounting.

SCV-100 Series Process Control Valves
For Steam, Hot and Cold Liquids -40° to 450°F up to 500 psi
These valves are designed for low pressure service and where compactness is desired. The stem and disc are machined from a single piece of stainless steel. Seat rings are stainless steel and are of drop-in variety. The upper seat which is of cage design, also serves as a diverter to help direct the flow through the valve. The stem packing consists of a single ring of glass reinforced PTFE with an integrally confined spring to eliminate the need for manual adjustments of packing. Because only one seal is used, the cavity for the seal in the body is shallow and the stem bearing length is correspondingly longer. A spiral wound gasket consisting of stainless steel and filler material is utilized to seal the upper seat.
