JDFQ4LX Low Resistance Anti fouling Isolation Valve

The bottom valve,also known as the reverse stop valve, is a low-pressure plate valve, whose function is to ensure the single flow of liquid in the suction pipe, so that the pump works normally when the pump stops working for a short time, so that the liquid can not return to the water tank, and the suction pipe is filled with liquid to facilitate the start of the pump.

The valve is a kind of energy saving valve, generally installed in the bottom valve of the water pump suction pipe to limit the return of liquid water in the water pump pipe, mainly used in the pumping line.

Brass foot valve by the valve body, cover, disc, sealing ring and gasket and other components, the foot valve disc has a single, double and multi - disc and other types.After the bottom valve is connected to the pipeline, the liquid medium enters the body from the direction of the valve cover. The pressure of the liquid acts on the disc, making the disc open to allow the medium to flow through.

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.

A gate valve is a gate with an opening and closing element, and its movement direction is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and it varies depending on the door parameters, usually 5 °. When the medium temperature is not high, it is 2 ° 52 '. Improving its processability and compensating for the deviation in the sealing surface angle during the processing, this type of gate is called an elastic gate.

The HQ41X-10/16, HQ44X-10/16 wear-resistant ball check valves and HQ45X multi ball check valves produced by our factory use rubber wrapped rolling balls as valve discs. Under the action of the medium, they can roll up, down, left and right on the integral slide inside the valve body to open or close the valve. Silent closure, no water hammer generated, good sealing performance. The HQ41X slide ball check valve body adopts a full water flow channel, with high flow rate, low resistance, and a head loss 50% smaller than the swing type. It can be installed horizontally or vertically and can be used in cold water, hot water, industrial and domestic water pipeline systems. It is more suitable for submersible drainage sewage pumps, with a medium temperature of 0-80 ℃.

Product features: Multiple material pump head options: PVC, PTFE, stainless steel 304, stainless steel 316. The flow rate can be adjusted freely during operation. Structurally, completely leak free. Suitable for various acid and alkali resistant liquids. The use of high-quality PTFE and rubber composite membranes has strong corrosion resistance, greatly improving the service life of the membrane. Suitable for various acid and alkali resistant liquids. Can be installed on the medicine tank. Easy installation, easy maintenance and upkeep. High operational safety performance.

Overview of ZBSF stainless steel flange solenoid valve: The ZBSF stainless steel flange solenoid valve is an actuator used in an industrial process automation control system. It can automatically open or close after receiving an electric control signal to realize the on-off or flow adjustment control of the fluid in the pipeline. This series of solenoid valves can be widely used It is used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, machinery, electrical appliances, surface treatment and other production and research departments, as well as in people's daily life facilities such as bathrooms, canteens, and air conditioners.

Electronic temperature control regulating valve： The ZZWPE type self operated electronic temperature control valve (suitable for large caliber and heat transfer oil control), the biggest feature of this valve is that it only requires a regular 220V power supply, and utilizes the energy of the regulated medium to directly adjust and control the temperature of steam, hot water, hot oil, gas and other media.
