s
Symmetric or Canted Yoke –
G-Series actuators, with their scotch yoke design, are available with either symmetric or canted yokes, depending on break torque requirements.
s
Modular Design –G-Series砂锅排骨
actuators have available, field-rviceable drive, power, spring and override modules. The mod-ules are removable, rviceable and interchangeable while
mounted to the valve. Modules are available for parate purcha to reduce spare parts inventory (See page 8 for further details).
s
Safety – The patented Tension-Lok™ allows the safe installation and removal of the spring module in a manner that eliminates accidental relea of the spring force and reduces potential for incorrect installation, operation or misapplication of a reconfig-ured actuator.
s
Industry Leading Warranty
人力资源体系
– G-Series actuators are backed by a five year materials and workmanship warranty – the industry’s best.
s
Standardized – The shaft driven accessory inter-face conforms to NAMUR and is identical on all G-Series models, allowing standardization of accessory mounting hardware and installation practices.
s
Versatile – The G-Series actuator power and spring
modules can interchange easily, allowing for quick reversal of the fail-safe mode,while allowing the
addition of overrides, accessories and other modules (See page 8 for further details).
s
MSS or ISO Valve Mounting – The G-Series valve
interface meets the dimensional requirements of MSS SP-101 or ISO 5211 defined for each torque range.

Safe Spring Lock
Mechanism – Tension-Lok™
find函数
positively locks the spring module in place under load. Prevents spring module detachment from the drive module unless it is taken to a safe condition.
2
Reduced Wear –Powr-Swivl™
connects the piston rod with the guide block, compensating for side load deflection and reducing wear on rod, bearings and als (not available in G1models).
3
Positive Yoke Seal –
Acculine™ shaft drive assures a positive yoke al,maintains and eliminates accessory shaft side loads which helps maintain device integrity and prevents unintentional din-gagement of critical signal devices or controls.
4
Standardized Mounting –
The NAMUR mounting configuration allows standardization of mounting hardware for a wide range of shaft-driven accessories.
5
Replaceable Bearings –
Protect sliding and rotating components, with suitability for
either dry or lubricated working conditions.
6Better Alignment – Guide Block Thrust Bushing
aligns the guide block within the yoke arms to enhance the Powr-Swivl function.
7Reduced Axial Movement – Non-metallic thrust
bar prevents yoke pin axial movement, transferring axial loads directly to the drive module ca.
8
Internally Mounted Optional Overrides –
Hydraulic override cylinder module for spring-return models doesn’t increa actuator length. Design
positively parates power and override fluids. Options include speed controls, special trims, and pilot signal or power gas auto-dingage.

Corrosion Resistant Spring Module – Guided by lf-lubricating
alignment bearings. Fully enclod and supporting Tension-Lok, prevents potential operating personnel injury or equipment damage. Corrosion resistant to harshest environments.
10Easy Lifting – G4 and larger models equipped with eight lifting eyes
for safe actuator handling in three major planes during shipping, installation and removal.
11Environmental Sealing – Breather als out environment, meeting
IP 67M criteria. Normally clod 316 SS normally clod breather allows pressure equalization during operation.
12Accurate Drive Alignment – Actuator/Valve Interface with optional
centering ring, assures accurate alignment of output drive and valve stem.Female drive, with full length keyed connection, allows for valve/actuator mounting in a variety of orientations, when specified.

13Better Sealing – Vent Checks – Two drive module vent checks relea
overpressure and al, preventing dust, corrosive atmospheres and water ingress. Lower vent isolates valve stem leakage and provides a means of attaching fugitive emissions monitoring devices.
14Reduced Tubing Exposure – Inboard port location minimizes
exposure of supply tubing, reducing opportunity for mechanical damage on spring-return units. Pneumatic and hydraulic units have NPT ports.Consult factory for options.

15Full Travel Adjustment – Bi-Directional Travel Stops integral to the
actuator, the stops allow 80°to 100°total travel adjustment. Cylinder-mounted extended travel stops are optional.
16Corrosion Resistant Tie Bars – Featured on pneumatic power
modules, the tie bars are protected from corrosion and physical damage. Also center the piston in the cylinder bore to prevent metal-to-metal contact.
