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.

High Pressure Valves
Sinclair Collins® 3-Way Two-Pressure Hydraulic Control Valves are widely used in press operations or in other similar applications where low and high operating pressures are employed. Diaphragm-operated, they may be actuated by manually, electrically or mechanically operated air valves. They are designed to control two pressure systems where the low pressures range from 50 to 2000 psi and high pressures up to 3500 psi.

Process Control Valves
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.
