Sinclair Collins® Process Control Valves
For Steam, Hot and Cold Liquids -40° to 450°F up to 500 psi

Catalog SCV-100/USA April 2001

The Diaphragm Operated Valves on the following pages are designed for directing, diverting or mixing liquids or gases. They provide a pressure range up to 500 psi (34 bar) and are designed to handle temperatures ranging from -40°F to 450°F (-40° to 232°C).Saturated Steam Pressure Ratings: The maximum operating pressures listed for individual valves in this section may be used as the recommended Saturated Steam Pressure Rating. Line mounted 2- and 3-way, normally-open and normally-closed valves are available. This series of valves is designed primarily for use with steam and hot or cold water, but may be used to control other fluid media that arecompatible with the materials used in their construction. They are widely used with pressurized gases or on vacuum service despite the slight leakage that may occur when poppet-type valves with metal-to-metal seats are used in these services. When leakage is a problem, the use of the soft seated 400 psi (28 bar) valve is recommended. Many of both styles of valves are used on freon, air, nitrogen,carbon dioxide and other non-explosive services. The cylinder-operated manifold-mounted valves are designed for areas where multiple valve manifolding would simplify valve installations.

Applications

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 andcold 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. In manufacturing, these valves are being used to control steam, hot and cold water and vacuum in foam cup manufacturing, tennis ball andgolf ball manufacturing and for filling different size soap containers. They are used to control hot wax in candle making, for drawing a vacuum in glass making and as unloading valves on air compressors. They are used for temperature control in optical lens manufacturing and in extruder applications while applying plastic coatings on wire. In the foundry industry, these valves are used on patternspray-off equipment and to blend or add soaps and oils used in coremaking. They are being used in coolant systems for large boring and drilling machines, in pressed board and particleboard manufacturing for glue control to mixing tanks. They may also be found on sterilizer equipment in hospitals and dairies.
