Z45W Brass Manual Flange Gate Valve. Type:Z45W-16T. Size:DN40~600mm. Pressure:1.0~2.5MPa. Material:Brass.

Design and manufacture according to JB/T3595 and other standards. The middle cavity of the valve adopts a pressure self-tightening sealing structure with good sealing performance, and the two ends of the branch pipe are welded structures. The sealing surface of the gate and the valve seat is made of hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance and scratch resistance. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance. The structure of the opening and closing parts can be designed into different forms such as single plate, double plate, parallel double plate, etc. according to user requirements.

Nominal pressure: PN1.0~32.0MPa. Nominal diameter: DN15~100, NPS 1/4 ~4". Connection method: flange, butt welding, thread, etc. Drive mode: manual, pneumatic, electric, hydraulic, etc.

Worm gear fully welded ball valve, there will be no external leakage, etc., because the valve seat is composed of carbonized Teflon seal ring and coffee spring, it has strong adaptability to pressure and temperature changes, and it will not occur within the marked pressure and temperature range. Any leaks. The processing of the sphere is tracked and detected by an advanced computer detector, and the processing precision of the sphere is high. Since the valve body material is the same as the pipe material, there will be uneven stress, no deformation due to earthquakes and vehicles passing the ground, and the pipe is resistant to aging. The body of the seal ring is made of PTFE with a content of 20% C (carbon) to ensure no leakage (0%).

The structure of the copper globe valve is simple, and the manufacture and maintenance are more convenient.

It is suitable for cutting off or connecting pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and electric power industries with nominal pressure PN1.6~16MPa and working temperature -29~550?.

Lift check valve refers to the valve that automatically opens and closes the valve flap depending on the flow of the medium itself to prevent the medium from flowing back. It is also called check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is a kind of automatic valve, its main function is to prevent the back flow of the medium, prevent the pump and drive motor from reversing, and release the container medium.

Swing check valve is also called one-way valve or check valve, its function is to prevent the medium in the pipeline from flowing back. The valve that opens or closes on its own by the flow and force of the medium to prevent the medium from flowing back is called a check valve. Swing check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in the pipeline.

Butterfly valve, also called flap valve, is a kind of regulating valve with simple structure. The butterfly valve that can be used for switching control of low pressure pipeline medium refers to the closing part (disc or butterfly plate) as a disc, which rotates around the valve shaft to achieve opening and closing. A kind of valve.

Type: D71F46. Size: DN40~1200mm. Pressure: 1.6MPa. Material: Cast iron, Cast steel, Stainless steel.
