Product Details

Features

01. Large output torque, stable and reliable action, suitable for all kinds of rotary valves
02. Cylinder internal wall and piston shaft are chromium plated, with outstanding abrasion resistance
03. Air source pressure: Normal 5～8bar, special 3～5bar
04. Ambient temp.: Normal type -20～80℃ (code: C)
High temp. type -20～180℃ (code: G)
Low temp. type -40～60℃ (code: D)
05. Sealing material: Normal---NBR (code: N)
special high temp.---fluororubber (VITON, code: V)
special low temp.---silicone rubber (code: G)
06. Manual operating mechanism optional
07. To realize optional automatic control function, accessories such as limit switch, travel switch, proximity switch can be mounted on the top
08. Through adjusting bolt to realize fully open/closed ±5° micro control
(As shown in the diagram: The left adjusting bolt adjusts the travel along opening direction, and the right adjusting bolt adjusts the travel
　 along the closing direction stroke)
09. Equipping positioner can realize the control function

Open/Closed Time Table

Note: The ambient temp. above is 20℃, air source pressure is 0.5MPa with empty load, just for reference.

Cylinder Volume

Notes:

The data above is the calculating result under the ambient temp. 20℃,and the calculation data of air consumption might have deviance from the actual consumption.
A and B represent two cylinders of the actuator. Cylinders A and B of the doubleacting actuator take in air at the same time, while only cylinder B of the singleacting actuator take in air.

Cylinder Air Consumption Calculation

Double acting cylinder calculation formula for air consumption:

Single acting cylinder calculation formula for air consumption:

V: Air consumption, L/min P: Air source pressure, KPa n: Open/closed times/min (open/closed travel times) A,B: Cylinder volume (see table above) 1MPa=1000KPa

QWS Double Acting Actuator Type Selection Configuration Table【the torque in shadow is standard selection as preferred consideration】

QWD Single Acting Actuator Type Selection Configuration Table【the torque in shadow is standard selection as preferred consideration】

Note: The data above is configuration of cylinder’s air source pressure 5bar&valve PN1.6MPa under standard torque, just for your reference.
