The gate of the big size cast steel gate valvee moves linearly with the valve stem, which is called the lift gate valve (also called the open gate valve). Usually, trapezoidal threads are provided on the lifting rod, and the rotary motion is changed into a linear motion by the nut at the top end […]
Y-type Strainer is mainly composed of nozzle, main pipe, filter, flange, flange cover and fasteners. When the liquid enters the basket through the main tube, the solid foreign particles are blocked in the filter blue, and the clean fluid passes through the filter basket and is discharged from the filter outlet. The Y-type Strainer is […]
The globe valve, also called the gate, is the most widely used type of valve. Due to its own performance, it is not only suitable for medium and low pressure, but also for high pressure. Next, stv will specifically introduce what is a globe valve? What are the characteristics of the globe valve? A globe […]
Ball valves are mostly spherical in shape and generally have long switches for the user to manipulate the switches of the ball valves. With the development of technology, in addition to manual control of the switch, the current ball valve will be more efficient and convenient through automatic control. Due to its low cost, wide […]
The high-platform ball valve is an evolution of the ordinary ball valve. It has all the functions of a common ball valve, and is more beautiful and more refined than a normal ball valve. It is very convenient to install electric or pneumatic actuators with platform ball valves. It also saves costs without racks, improves […]
The passage of the forged steel check valve fluid through the lift check valve is also narrow, so the pressure drop through the lift check valve is larger than that of the swing check valve, and the flow rate of the swing check valve is limited. Very few. Check valves are generally suitable for cleaning […]
The suitable working temperature of WC6 is -29 ~ 540 °C, and the suitable working temperature of WC9 is -29 ~ 570 °C. Both specifications are chrome-molybdenum steel, and the mechanical properties of the two are basically the same, with the same tensile strength, yield strength and elongation at room temperature. The Cr-Mo high temperature […]
The first type is a bolt-type bonnet, which is connected by a concave-convex surface, and is made of a stainless steel strip and a flexible graphite wound gasket, and can also be connected by a ring as needed. The second type is a welded bonnet that is welded by thread sealing and can be directly […]
The speciality and production of the integral flange forged steel valve, the integral flange forged steel valve is mainly applicable to the pipelines of various systems of the thermal power station, cutting or connecting the pipeline medium. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, the integral flange forged […]
The selection principle is as follows: 1. Forged steel globe valves should be used on the pipeline or device of high temperature and high pressure medium. Such as thermal power plants, nuclear power plants, high-temperature, high-pressure pipelines of petrochemical systems. 2. On the pipeline where the flow resistance is not strict on the pipeline. That is, […]
