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.
