HEP17 HEP16 HEP15 HEP Electric Pneumatic Diaphragm Valve Positioner With Yamatake KZ03-3A Air Filter Regulator

Overview of HEP-15 HEP-16 HEP-17 Valve positioner

HEP-15 HEP-16 HEP-17 Valve positioner: HEP single acting electric pneumatic valve positioner (including HEP-15 flameproof type, HEP-16 intrinsically safe type and HEP-17 waterproof type) is the main accessory of CV3000 series new regulating valve. Hep series single acting electric valve positioner is a product successfully developed by our factory with the latest foreign design. Its technical performance has reached the level of similar foreign products, and has passed the inspection of "national instrument explosion-proof safety supervision and inspection station", and obtained the national explosion-proof certificate.

HEP single acting electro pneumatic valve positioner (including HEP-15 explosion-proof type, HEP-16 intrinsically safe type and HEP-17 waterproof type) is used to turn the electrical signal output by the regulating device into the gas signal driving the action of the regulating valve, and has the function of valve positioning, that is, overcoming the friction force of the valve stem and offsetting the unbalanced force caused by the change of the adjusted price and quality pressure, so as to make the valve opening correspond to the control signal output by the regulating device and realize correct positioning. Because the positioner has explosion-proof structure, it can be used in explosion dangerous places.

Technical parameterof HEP-15 HEP-16 HEP-17

1. The introduction of foreign advanced design has the characteristics of high reliability, small volume and light weight.

2. The magnetoelectric component adopts a new moving coil structure, which is reliable, stable and linear.

3. In addition to the explosion-proof junction box, the shell cover can be opened for adjustment and maintenance in the dangerous area.

4. The range and zero adjustment buttons adopt hand wheel type, which is convenient to adjust and equipped with locking device.

5. It is equipped with mounting plates and accessories matching with various types of actuators, so it is easy to install and adjust.

6. Explosion proof performance: intrinsically safe explosion-proof grade IA Ⅱ CT5 explosion-proof grade D Ⅱ CT6.

7. Compact structure, precise and reliable. The parts of this product are precision die cast, and the manufacturing process of shape and internal structure is exquisite. After optimized combination design, the whole machine has a compact structure, which is treated with stainless steel fasteners and advanced spray molding process The production marks are permanent and have good anti-corrosion performance.

8. This positioner can be used as required A movable adjustable damping mechanism is adopted to make the output flow adjustable.
