Manhole refers to the opening structure used for personnel to enter and exit equipment for installation, maintenance and safety inspection. It is mainly composed of short barrel (or short pipe), flange and manhole cover with handle. For safety inspection, the number of manholes and the minimum size required for pressure vessels are shown in "Inspection Holes". - Wenzhou Yuzheng Valve Co.,Ltd

Three-way directional valve is used in solid material (powder, particle, powder mixture, flake material) conveying system for switching the material flow in the pipeline of special equipment, three-way commutator three channels are arranged at an Angle, one into two out or two into one out. - Wenzhou Yuzheng Valve Co.,Ltd

X43W two-way cast iron flange plug valve is a rotary valve with a closing part or plunger shape. By rotating 90 degrees, the channel opening on the valve plug is made to communicate with or separate from the channel opening on the valve body to achieve opening or closing. The shape of the valve plug of the plug valve can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; while in the conical valve plug, the channel is trapezoidal.

Globe valve, also known as the cut-off valve is the most widely used type of valve, it is popular because of the opening and closing process between the sealing surface of the friction is small, more durable, open height is not large, easy to manufacture, easy maintenance, not only for low and medium pressure, but also for high pressure. The closing principle of the globe valve is to rely on the pressure of the valve bar, so that the valve sealing surface and the valve seat sealing surface close to prevent the flow of media. Globe valve only allows the medium to flow in one direction, the installation of directional. Globe valve structure length is greater than the gate valve, while the fluid resistance, long-term operation, sealing reliability is not strong.

Coupling, is a groove type pipe card, mainly used in dairy products, beer, food, beverage, pharmaceutical, biological engineering and other industrial fields.
