Specification ning luklukan:
| Materyal | Temperatura | Gamitan ing pamaglarawan |
| NBR | -23°C ~ 82°C | Ing Buna-NBR:(Nitrile Butadiene Rubber ) atin yang masanting a tensile strength ampo resistance keng abrasion. E ya naman resistance keng hydrocarbon products. Metung yang masanting a general-service a materyales para gamitan keng danum, vacuum, acid, asin, alkalines, taba, oils, greases, hydraulic oils ampo ethycolilely. Ing Buna-N e ya malyaring gamitan para keng acetone, ketones ampo nitrated o chlorinated hydrocarbons. |
| Oras ning pamamaril-23°C ~120°C | ||
| EPDM | -20 °C~130°C | General EPDM rubber: metung yang masanting a general-service synthetic rubber a gagamitan keng mainit a danum, inuman, milk product systems ampo deng ating ketones, alcohol, nitric ether esters ampo glycerol. Pero ing EPDM e ya malyaring gamitan para kareng hydrocarbon based oils, minerals o solvents. |
| Oras ning pamamaril-30°C ~ 150°C | ||
| Viton | -10 °C~ 180°C | Ing Viton metung yang fluorinated hydrocarbon elastomer a maki masanting a resistensya kareng keraklan a hydrocarbon oils ampo gases ampo reng aliwang petroleum a produktu. E ya malyaring gamitan ing Viton para keng steam service, mapaling danum a maygit 82°C o concentrated alkalines. |
| PTFE | -5°C ~ 110°C | Ing PTFE atin yang masanting a chemical performance stability ampo ing babo na ali ya malagkit. At the same time, atin yang masanting a lubricity property ampo aging resistance. Masanting yang materyal a gamitan kareng acid, alkali, oxidant ampong aliwang corrodents. |
| (Inner liner EDPM) | ||
| PTFE | -5°C~90°C | |
| (Inner liner NBR) |
Operasyun:lever,gearbox,electrical actuator,pneumatic actuator.
Kaasalan:
1.Stem head design ning Double "D" o Square cross: Manyaman yang ikonekta kareng miyayaliwang actuators, magdalang mas marakal a torque;
2.Two piece stem square driver: No-space connection apply to any poor conditions;
3.Body alang Frame structure: Ing luklukan malyari yang mikawani ing katawan ampo ing fluid medium eksaktu, ampo manyaman ya keng pipe flange.
