As a  Butterfly Valve Supplier , share with you. As a kind of valve that can be used to adjust and cut off the medium flow of pipelines, butterfly valves are widely used in industrial production, so their demand is also very large, and some manufacturers are manufacturing hard for their own benefit. When sealing butterfly valves, cut corners and cut materials to reduce production costs, resulting in some products of poor quality on the market. Customers who purchase these products will think that the quality of hard seal butterfly valves is not good, and they should not choose hard seal butterfly valves in the future. This view is wrong, in fact, the quality of standard hard seal butterfly valve is very good. Lug Type Butterfly Valve When we choose to buy a butterfly valve, we must clearly know where it was purchased, and we need to understand the parameters of each environment. When choosing the appropriate product according to these parameters, and in addition to looking a...

The selection of  Gate Valve  is mainly based on the following two points: Machine selection is a complicated process, which is a big problem for many people. Only by choosing the right product can it play its greatest role and maximize its value. Next,  Gate Valve Supplier  will deeply analyze the selection techniques of gate valves for everyone, let's take a look! DIN F5 Gate Valve Gate valve selection techniques mainly have the following two points: 1. Structure and working principle of radiator gate valve The temperature control in the user's room is realized by the radiator thermostatic control valve. The radiator thermostatic control valve is composed of a thermostatic controller, a flow regulating valve and a pair of connecting pieces, wherein the core component of the thermostatic controller is a sensor unit, that is, a temperature package. The temperature package can sense the change in ambient temperature and produce volume changes, drive the v...

Gate Valve  is an opening and closing gate. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel and so on. The gate has rigid gate and elastic gate. According to the different gates, the gate valve is divided into rigid gate valve and elastic gate valve. As a  China Gate Valve leading Supplier , share the precautions with you: 1. The hand wheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited. 2. The double gate valve should be installed vertically (that is, the valve stem is in the vertical position and the handwheel is at the top). 3. The gate valve with bypass valve should open the ...

As a  Flange Check Valve Manufacturer , share with you. Swing Check Valve   1. In order to prevent the medium from flowing backward, check valves should be installed on equipment, devices and pipelines; 2. The check valve is generally suitable for clean media, and should not be used for media containing solid particles and large viscosity; 3. Generally, horizontal lifting check valves should be used on horizontal pipes with a nominal diameter of 50mm; 4. straight-through lifting check valve can only be installed in horizontal pipelines; 5. For the inlet pipeline of the pump, a foot valve should be selected. The foot valve is generally only installed on the vertical pipe of the pump inlet, and the medium flows from bottom to top; 6. Lifting type has better sealing performance than swing-opening type, and has larger fluid resistance. It should be installed on horizontal pipelines horizontally and vertically on vertical pipelines. 7. The installation position o...

As a  Ball Check Valve Leading Supplier , share with you. 1.  Swing Check Valve : The disc of the swing check valve is disc-shaped and rotates around the rotation axis of the valve seat channel. Because the channel inside the valve is streamlined, the flow resistance is smaller than that of the lift check valve, which is suitable for Velocity and flow do not change in large diameter occasions, but it is not suitable for pulsating flow, and its sealing performance is not as good as the lifting type. Swing check valve is divided into three types: single, double and multiple. These three types are mainly divided by the valve diameter, in order to prevent the hydraulic shock when the medium stops flowing or flows backward. 2. Lift check valve: check valve with valve disc sliding along the vertical centerline of the valve body. Lift check valve can only be installed on horizontal pipelines. On high-pressure small-diameter check valves, the valve disc can be a ball. . The shape...
