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.
