Seat Specification:
Material | Temperature | Use Description |
NBR | -23℃ ~ 82℃ | Buna-NBR:(Nitrile Butadiene Rubber ) has good tensile strength and resistance to abrasion.It is also resistant to hydrocarbon products.It is a good general-service material for use in water,vacuum,acid,salts,alkalines,fats,oils,greases,hydraulic oils and ethylene glycol. Buna-N can not use for acetone,ketones and nitrated or chlorinated hydrocarbons. |
Shot time-23℃ ~120℃ | ||
EPDM | -20 ℃~130℃ | General EPDM rubber: is a good general-service synthetic rubber used in hot-water, drinks, milk product systems and those containing ketones, alcohol, nitric ether esters and glycerol. But EPDM can not use for hydrocarbon based oils, minerals or solvents. |
Shot time-30℃ ~ 150℃ | ||
Viton | -10 ℃~ 180℃ | Viton is a fluorinated hydrocarbon elastomer with excellent resistance to most hydrocarbon oils and gases and other petroleum-based products. Viton can not use for steam service, hot water over 82℃ or concentrated alkalines. |
PTFE | -5℃ ~ 110℃ | PTFE has good chemical performance stability and surface will be not sticky.At the same time, it has good lubricity property and aging resistance. It is a good material for use in acids, alkalis, oxidant and other corrodents. |
(Inner liner EDPM) | ||
PTFE | -5℃~90℃ | |
(Inner liner NBR) |
Operation:lever,gearbox,electrical actuator,pneumatic actuator.
Characteristics:
1.Stem head design of Double “D” or Square cross:Convenient to connect with various actuators,deliver more torque;
2.Two piece stem square driver:No-space connection applies to any poor conditions;
3.Body without Frame structure:The seat can separate the body and fluid medium exactly,and convenient with pipe flange.
