IP65 Single Acting Pneumatic Valve Actuators Toothed Strip 12v

DINKONDA GLOBAL Power Plants Special GT Series Double Acting/single Acting (spring Reset) 90 ° Angular Stroke Dual Piston Toothed Strip Pneumatic Actuator

Product Overview
The GT series angular stroke pneumatic actuator is a gear rack type pneumatic drive device, which adopts a dual piston gear tooth strip transmission structure and outputs a 90 ° angular stroke. It is mainly matched with angular stroke valves such as ball valves, butterfly valves, and plug valves to achieve on/off control of pipeline media. It is divided into two types: double acting and single acting (spring reset). Relying on clean compressed air as a power source, it has the characteristics of fast action, stable torque, and high reliability, and is widely used in industrial pipeline self-control systems such as chemical, environmental protection, water treatment, heating, gas, and power plants.

Structural Composition
1. Aluminum alloy cylinder assembly
The cylinder barrel is made of extruded aluminum alloy, with hard anodized treatment on the inner wall. The surface is wear-resistant, corrosion-resistant, and has low friction resistance; The black aluminum alloy end caps at both ends are locked with high-strength bolts, and the overall structure is compact and lightweight, suitable for narrow installation spaces of valves.

2. Double piston gear rack transmission mechanism
The cylinder body is symmetrically arranged with double pistons, which are connected to a rack and precisely mesh with the central output gear, converting the linear reciprocating motion of the pistons into a 90 ° rotation of the output shaft.
Double function: alternate intake of air from both sides of the valve to achieve full open and full close action of the valve;
Single acting: Equipped with a built-in spring component, the ventilation driven valve operates, and the spring automatically resets to the preset safe position in case of gas loss.

3. Output shaft and limit adjustment component
Top output square shaft, output flange interface in accordance with ISO5211 international standard, can directly connect to various angular stroke valves; The cylinder body is equipped with two sets of adjustable limit bolts on the side, which can perform small calibration for 0 ° and 90 ° angles, meeting the on-site installation angle adjustment requirements.

4. Valve position indication installation base
Reserve a position indicator installation position above the cylinder block, which can be equipped with a visual position indicator to visually display the fully open/fully closed status of the valve; Standardized accessory installation holes are reserved on the surface of the cylinder body for easy installation of solenoid valves, limit switches, and air filter pressure reducing valves.

5. Sealing assembly
The piston and end cap seals come standard with NBR nitrile rubber to ensure cylinder airtightness; FKM fluororubber seals can be replaced as needed to adapt to high-temperature and weakly corrosive media conditions.

Core Features
1. Double piston gear rack structure, stable torque output
The symmetrical piston has uniform force, small opening and closing impact, small transmission backlash, constant output torque, and long product service life.

2. Two types to choose from, suitable for different safety working conditions
The double acting model has high torque and is suitable for conventional switch cut-off conditions; Single acting spring reset model, automatic reset when gas is cut off, meeting the requirements of process safety interlocking (customized for gas loss closing/opening).

3. Standardized universal interface, easy attachment expansion
The output flange follows the ISO5211 standard and has strong universality; It can be equipped with a complete set of automatic control accessories such as solenoid valves, limit switches, valve position feedback devices, pressure reducing valves, etc. Explosion proof accessories are optional and suitable for flammable and explosive working conditions.

4. The cylinder body is corrosion-resistant and wear-resistant, and easy to maintain
Anodizing treatment of aluminum alloy cylinder barrel, resistant to water vapor corrosion; Modular structure, easy disassembly and maintenance, and convenient on-site replacement of seals.

5. Flexible installation direction
Can be installed from multiple angles, compatible with various valve installation methods such as horizontal and vertical, to meet different pipeline layouts on site.
