－ 4 pistons pneumatic actuator －
Successful Case - USA. TOYOTA Fireproof Testing - patent No.ZL.200720019431.8

Design Characteristics:

Small: one third times smaller than the traditional double piston cylinder with the same torque force.
Energy-saving: 1.8-2.5 times more than double piston models in terms of savings of air consumption.
Quick-witted: one time faster than double piston models in terms of switching time.
Longevity: The short stretch distance of the piston highly raises the working time of the sealing elements.
Superior weather resisting property: After horniness oxidation treatment, the surface of aluminium alloy thing-in-itself is covered by metallic polyester coating. In the general low acid environment, it will keep non-corroding and nondiscolouring for 30 years.

－ 2 pistons pneumatic actuator －

Design Characteristics:

Wild application range:
1. Super big delivery outlet, packed by varied adapters, won't be troubled by different shaped valve handle in connecting with valves.
2. Super deep output shaft bearing bore won't be influenced by the height restriction of the valve handle.
3. Transducer switch ports at the bottom of the cylinder can convert and connect all non ISO5211 standardized pitch-rows in valve gallery.
Longevity: Unique structural design and processing technic among fellow traders; the sealing life and service life of the whole series products exceed respectively half million times and one million times.
Superior weather resisting property: After horniness oxidation treatment, the surface of aluminium alloy thing-in-itself is covered by metallic polyester coating. In the general low acid environment, it will keep non-corroding and nondiscolouring for 30 years.
