300 Class Globe Valve

Ratings
Sanco Valves must only be used in operating conditions within the appropriate ANSI pressure-temperature ratings for valve class rating and body/bonnet material (see Technical Data section).

Temperature Limitations
Sanco Valves Only use valves within the temperature limitations of their construction. Temperature limitations of body/bonnet materials, trim, bolting, packing and gaskets must all be considered. Special construction for extended service temperatures are available on application.

Material And Service [ ]
Sanco Cast steel bolted bonnet valves are available in a variety of body/bonnet materials and trims. General service recommendations for body/bonnet materials appear on page 32 and for trims on page 33. Specified materials should be compatible with the service.

The circular male and female bonnet joint is self-aligning andencapsulates the gasket. Our standard gasket is double jacketed metal.Valves in these classes are also available with spiral wound or ringjoint gaskets when specified.

Features

V-port trim has a more linear throttling curve than plug or ball discs, but none of these trims are recommended for continuous severe throttling which may require using a control valve. Pacific Valves will be glad to advise you on your application. Globe valves are available with a complete range of manual or remote actuators. See Actuators and Accessories sectionfor more detail.

Sanco Globe valves are used where throttling or both throttling and shutoff are required. They can also be used for on-off service, but because of high pressure drop, this is generally confined to applications where the valve is normally closed and pressure drop is not important when the valve is open.
Normally Sanco globe valves are installed with flow under the disc, but under certain conditions flow over the disc may have advantages. Standard globe valves, because they are designed for both throttling and shutoff, should not be used for prolonged throttling at less than 10% open. Internal damage can occur. Using a smaller valve or V-port trim to increasethe percent open will often solve this problem.
