Sanco Gate valves normally are handwheel operated, but are also available with gearing, electric motor actuators, or cylinder (pneumatic or hydraulic) actuators for remote operation. See Actuators and Accessories section for more detail.
Type And Size
Select the best type of valve for the intended service (gate, check, etc.). Sanco Gate and Globe valves are available with a selection of wedge or disc configurations for different services. Sanco Valves may be sized to match existing lines, but swing check and stop-check valves should also be sized according to flow conditions for maximum service life.
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.
