Aluminum Die casting Electro Pneumatic Positioner for quarter- turn control valves
Product Description
The Pneumatic Pneumatic Positioner YT-1000 series are used for
pneumatic valve actuators by means of pneumatic controller or
control systems with an output signal of 3 to 5 psi or split
ranges.
- The product can operate normally in very extreme environment,
such as vibration and temperature.
- The durability has been proven after testing 2 million cycles at
the minimum.
- Response time is very short and accurate.
- Simple part change can set 1/2 Split Range.
- It is economical due to less air-consumption.
- Direct / Reverse action can be set easily.
Fluitech positioners are used to control quarter- turn control valves such as butterfly and ball valves (standard and segmented) and its sensitive two-stage relay makes it ideal for precise damper control applications. Specify whenever valve positioning and sensitivity is critical.
For modulating control of valve positions, it automatically positions the valve to precise angles between 0° and 90° in response to a pneumatic input signal. The standard positioner is Double Acting but can be easily converted to Single Acting/Spring Return. It also has Split Range capabilities and an easy to adjust Span and Zero.
