Product Overview The V230 series self operated pressure regulating valve is an energy-saving control valve that relies on the pressure of the medium itself and does not require external energy for self control. It is used as a pressure control device for gases, liquids, and steam temperatures (≤ 350C) and other media. Product Features Maintenance-free, self pressure control of the medium, no need for external energy, significant energy-saving effect, stainless steel corrugated pipe pressure balance type, low imbalance force, high sensitivity, support for internal and external pressure setting points with a wide range, and can be easily adjusted by adjusting the nut. The actuator and spring can be assembled at will, thus achieving multiple adjustment ranges for high sealing requirements. The use of soft sealing valve core standard low noise valve core for higher noise reduction requirements, Special models with noise cancellers can be used with standard modular design, high level of standardization, and multiple combination controls can be achieved through combination components

Constant pressure, efficient, energy-saving, comfortable Four core technologies: permanent magnet synchronous motor, non-inductive FOC vector drive technology, diaphragm pressure tank technology, check valve to eliminate water hammer.

Characteristics of straight through diaphragm valves: The most prominent feature is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, preventing the valve stem, valve disc, and other parts located above the diaphragm from medium corrosion, eliminating the packing sealing structure, and avoiding medium leakage.

Overview of Pneumatic Flanged Metal Hard Seal Butterfly Valve: D373H wafer type metal hard seal butterfly valve, also called flap valve, is a simple regulating valve, and it can also be used for on-off control of low-pressure pipeline media. Wafer metal hard seal butterfly valve is a kind of valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and adjust the fluid passage. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully opened.

Aluminum alloy characteristic ability of high temperature butterfly valve, apply pressure range is higher also, nominal valve size is big, the body is made of carbon steel, the valve plate seal aluminum ring is used to replace the rubber ring, apply to the hvac, central air conditioning, fluctuation of complete sets of equipment, lack of application in the: water, gas, oil, chemical industry, metallurgy, energy, shipbuilding, electric power, petroleum, water treatment, construction and other industries.

Electric regulating valve is a valve used to regulate fluid flow, which can achieve flow regulation by driving the valve opening change through an electric actuator. Electric control valves are usually composed of valve bodies, electric actuators, controllers, and other components [1]. The structural diagram can refer to relevant design manuals or product samples, generally including valve sealing surfaces, valve seats, valve cores, valve discs, and other parts. The working principle of an electric regulating valve is to output and control signals from the electric actuator through a controller, thereby achieving valve opening adjustment. When it is necessary to adjust the fluid flow rate, the controller will issue a command to the electric actuator, which drives the change in valve opening through an internal mechanism to change the fluid flow rate

H61Y-200, H61Y-250, and H61Y-320 high-pressure power station check valve branch pipes have welded structures at both ends, and the welded joints can be made according to standards or user requirements. They are suitable as devices to prevent medium backflow in high-temperature and high-pressure water, steam, oil, and superheated steam pipelines in thermal power plants, petrochemicals, metallurgy, and other industries. One is an imported type that follows the standards of ANSIB16.34 and JIS E101; Another type is the national standard type of Jb3595 standard. The temperature and pressure levels it follows are consistent, and there is a certain exchange relationship in some pipelines. The central part adopts a pressure self tightening type without a valve cover, which has good sealing performance under high temperature and pressure conditions. There are two types of materials for self sealing rings: one is low-carbon steel, and the other is flexible graphite clamp 316 wire (mesh). Weld the sealing surface with drill based hard alloy. The processed pure metal layer is ≥ 3mm, which has wear resistance, high temperature resistance, corrosion resistance, scratch resistance, and long service life.

Product features: The most outstanding feature is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, disc and other parts above the diaphragm are free from medium corrosion, and the packing sealing structure is omitted, and the medium leakage will not occur.

The automatic exhaust valve has the advantages of beautiful appearance, stable performance, convenient installation and maintenance, no power consumption, and energy conservation. Widely used in hot water heating systems, hot water heating pipeline systems, air conditioning cold water systems, water treatment systems, hot water boiler room piping systems, and other cold and hot water systems, installed at the highest point of the pipeline or equipment to automatically eliminate all gases in the pipeline and ensure normal operation of the pipeline. Automatic exhaust valves include ZP multi-purpose automatic exhaust valve, single port automatic exhaust valve, and dual port automatic exhaust valve
