Valves are a critical component of any operation. Based on the pressure, temperature or flow measurement, a valve is used to control the process by opening or closing the valve, to keep the process variable as close as possible to the desired levels. Valves can be manual valves or control valves. The manual valve has either a hand-wheel or lever and can be any of multiple types, with ball, gate, globe being commonly used types. Control valves are pneumatically or electronically operated and thus result in precise control. In addition, control valves can be operated remotely. Fisher, Crosby, Tyco, Keystone, Fasani, Virgo, Asco, Aira, Bray and Brodie valves are perfect for a broad variety of applications.
