Model Number

PURETORQ Pneumatic Rotary Vane Actuator (Double Ac

Item No. : 2nd Generation VDA Series

Product Name : 2nd Generation PURETORQ Pneumatic Rotary Vane Actuator (Double Active)

Description :
PURETORQ invented and patented its vane-type, fixed seal, rotary pneumatic actuator, recognizing the need for long lasting, quarter-turn valve actuation with 100~ 6800 in-lb (11.3~765 N-m) double acting torque output.

Specification :
Model: VDA200, VDA400, VDA700, VDA1700, VDA3800, VDA6800
Inlet Air supply:
30~120 PSIG (2.07~8.28BAR) for double acting mode
Double acting torque output: 100~ 6800 in-lb (11.3~765 N-m)
Operation Temperature:-20º C~+60º C
Lifespan:1 million times
Materials:
Housing: Glass Reinforced Polyamide
Vane: Glass Reinforced Polyamide
Tri-seal: Polyurethane
Shaft: 304SS
Dual VDI/ VDE 3845 and ISO 5211 mounting pad
Direct NAMUR mounting pad for solenoid


Features :
‧Dual output drives: Independent dual ISO patterns with corresponding female star shape drive on each actuator, i.e. F03/F04 on the VDA100 and VDA200. F04/F05 on VDA400, F05/F07 on VDA700, F07/F10 on VDA1600, F10/F12 on VDA3800 and F12/F14 on VDA6800.
‧Double NAMUR VDI/VDE3845 mounting pad: Standard interface for limit switches and positioners.
‧Direct NAMUR mounting pattern for solenoid valves
‧Integrated shaft & vane: The shaft and vane are virtually one unit with zero mechanical hysteresis.
‧Fixed Seal: Patented design, enhancing reliability and actuator life.
‧Simple Construction: Reducing costs and maintenance.
‧Composite Material: Exceptional mechanical strength and corrosion resistance.
‧Rotary to rotary operation instead of linear to rotary: All the torque is delivered directly to the valve, no loss due to friction or translation of linear motion into rotary motion.
‧External spring return unit: Less than 10% torque decay over 90 degree operation.
‧Easy adjustable end stops: End stops providing 90° +/- 4° of travel adjustment.
‧Thrust bearing support of the vane: Eliminates possible damage due to end loading.
‧Vane is supported independently of the seal allowing the use of a more flexible seal material, thus reducing internal friction dramatically.
‧Nickel plated steel for all metal parts as standard
‧Stainless Steel available as an option: A2-70 bolting and 304SS inserts are available as an option.
‧Full range of universal mounting brackets and couplers: A wide variety of universal mounting brackets are available with the full range of ISO 5211 bolting patterns. Couplers are available to suit all configurations.
