VTX Series Stainless Steel Pneumatic Actuators

The VTX Series Stainless Steel Pneumatic Actuator offers configurations of spring return and double acting models with heavy-duty pinion, one-piece stainless alloy shafts. This unit is available for mounting iwth heavy duty spring conforming to ISO 5211. Simple conversion from double acting to a spring reutrn actuator can be completed by interchangeable modules with heavy duty bearings and NAMUR-slotted shafts.

Designed with extensive customer feedback providing these benefits:

• High performance and high reliability
• Fully compliant with the latest international standards and regulations
• More applicable to a wide range of specifications and higher cost performance
• Compact design is better suited for a variety of industrial applications

Structure:

1. Integrate and compact design utilizes the same body and end caps for the same double acting and spring return actuator models. It also benefits less spare parts inventory and is greatly convenient for customers’ field application by adding or removing spring cartridges.
2. Fully compliant with the latest international standards including ISO5211,DIN3337 and VDI/VDE3845, etc. Fully compliant with NUMAR standard and interchangeability, convenient to replace or mount accessories including solenoid valves, limit switches.
3. Apply rack and pinion with double pistons in advantages of compact structure, high cycle life, and swift operation. The piston tooth surface processed by CNC machining center performs with optimized gearing efficiency and transmission precision, as well as stable operation and reliable performance. It is convenient to switch rotation direction only by inverting the pistons for symmetrical mounting position design.
4. Dual independent travel stoppers can be conveniently and precisely implement±5°- adjustments externally in two directions, allowing actuators in alignment with valve on both the opening and closing phases of the stroke.
5. The composite bearings and guides on pinion and piston ensure precise operation, low friction and high life cycle, preventing output shaft from fractures
6. Rack and pinion tooth in high precision is designed in outstanding tooth profile ratio to realize less clearance, accurate drive and high output power.
7. Modularized preload spring cartridges with special coating is applicable to a wide range of scenarios with high security and anti-corrosion.
8. High-quality bearings are of reliable sealing, low friction, high cycle life and wide range of application temperature.
9. All of the internal and external fasteners are made in long term corrosion-resistant stainless steel.
10. Multifunctional position indicator with slot in compliance with NAMUR standard offers simplicity and clarity for visual indication. Connection to a variety of standard and common sensors can be easily realized.
11. Under normal operating conditions, the safety factor of 20%-30% increase of valve torque should be considered when selecting double-acting actuators.
12. Under normal operating conditions, the safety factor of 30%-50% increase of valve torque should be considered when selecting single-acting actuators.
