Product Description pneumatic control valve - Overview: From my factory developed the production of pneumatic control valve by a pneumatic multi-spring diaphragm actuator and low flow resistance composed of single-seat valve, high and low new executive body, light weight, easy equipment, new body structure compact, smooth flow, with a large flow coefficient. Pneumatic control valve operation stable, reliable operating characteristics, the tiny seat leakage, accurate flow characteristics, wide adjustable range of features. Pneumatic control valve is bound to the unique advantages of access to quality control results in a wide range of applications. Pneumatic control valve are standard, adjust a variety of species cut-off, bellows seal type, jacket insulation type. Pneumatic control valve suitable liquid temperature from -200 ℃ to + 560 ℃ in the range of various grades. Pneumatic control valve - Features pneumatic control valve, the amount applicable to the strict requirements of the leak valve before and after the low pressure and have a certain viscosity and containing a small amount of fiber media applications. Pneumatic flow control valve, according to the different switching modes can be divided into air-to-close normally open and normally closed gas open two. Air-to-close valve actuator and by positive action valve. When the input signal is changed to limit the pressure by the upper limit value, the valve from fully open to fully closed. Open air valve actuator and valve by reaction composition, when the input signal pressure by changing the lower limit of the upper limit, the valve from fully closed to fully open. Supporting Locator HEP series of electrical valve positioner Description Main features: 1, the introduction of foreign advanced design, high reliability, small size, light weight and other characteristics. 2, the magnetic component parts using the new moving-coil structure, reliable, stable, good linearity. 3. In addition to the explosion-proof junction box, in danger of opening the cover regional field adjustment and maintenance. 4, range, zero adjustment knob hand-wheel, easy to adjust, and with a locking device. 5, with the various types of actuators and accessories to match the mounting plate, so easy to install, easy to adjust. 6, explosion-proof performance: The explosion-proof rating iaⅡCT5 explosion-proof rating dⅡCT6. 7, compact, precise and reliable product parts precision casting, shape and internal structure of the exquisite craftsmanship, agencies optimized combination of design, compact structure, the use of stainless steel fasteners and advanced spray Schomburg Process. Manufacturing logo permanent and so on, have a good corrosion resistance. 8, the locator available upon request. Attached adjustable damping mechanism using the activity that has an adjustable output flow characteristics. Based on the above and other technical performance characteristics, so HEP series locators can meet different types of single-double action, positive. Counterproductive types of pneumatic actuators requirements. International level is more advanced and reliable and feasible technical performance and features.
