Among many valve products, gate valves and butterfly valves are very common valve types. However, many users do not know what the difference between the gate valve and the butterfly valve when selecting the type, and do not know how to choose these two valves. In response to this problem, the STV valve will introduce the difference between the lower gate valve and the butterfly valve to facilitate the user’s better selection. First distinguish by definition: The gate valve is one of the most common on-off valves. It is connected (opened) by means of a shutter (ie, the opening and closing member, the opening and closing member in the gate is called a gate or gate, and the gate is called a gate seat). Truncate (fully close) the media in the pipeline. It is not allowed to be used as a shut-off. During use, the gate should be prevented from being opened slightly. The erosion of the medium flowing at high speed will accelerate the damage of the sealing surface. The ram is used as a l...

API 600 1500LB Pressure Seal Gate Valve,WCB Body.6 Inch,BW End Model:Z61Y-1500LB-WCB-6 API 600 1500 LB Pressure Seal Gate Valve is in accordance with API 600, the High Pressure Seal Gate Valves has a beautiful shape, compact structure, reliable sealing. Valve for the Class 900 lb-Class 2500 lb various tubes on the road. High-pressure self-sealing valve has the following advantages: The pressure seal valves are designed for service of high temperature and high pressure and are widely used in fossil fuel power plant. Compared with bolted bonnet joint valves, it provides absolute reliable sealing of the bonnet joint, so that the pressure seal valves are more compact and rigid as well as maintenance cost-effective at high temperature and high pressure service. This kind of gate valve is not only characterized as simple structure and reliable usage, but also able to create slight flexible deformation to compensate the deviation of the sealing face angle generated during proces...

It provides an economical solution and is recommended for applications where damage to valves and other related mechanical equipment needs to be avoided. Pipeline debris including dirt and scale is often the cause of failure, damage, energy loss and a reduction in productivity.Stainless Steel Y Type Flange Strainer are typically used in applications where the amount of solids to be removed is small, and where frequent clean-out is not required. They are most often installed in gaseous services such as steam, air, nitrogen, natural gas, etc. STV Valve Technology Group Co., Ltd is a professional leader China Stainless Steel Y Type Flange Strainer ,Flange Y Type Strainer,Flange strainer,Y type strainer,WCB Y type Strainer,PN16 Y type strainer manufacturer with high qua...

API 602 Y-Pattern Globe Valve, A105N, 1 Inch, 2500 LB, SW End Model:PJ65Y-2500LB-A105N Our API 602 Y-Pattern Globe Valve is mainly suitable for various system pipes of thermal power stations, cutting or connecting the pipeline medium. Applicable medium. Valves compared to non-corrosive media such as forged steel vapors are characterized by high temperature, high temperature and high pressure compared to other products. The unique self-sealing design pressure is higher, and the seal is more and more. Due to the technical characteristics of the performance, the special conditions of the working conditions make the product also form a feature that cannot be replaced by other products. There are three types of socket welding Y-forged steel globe valve body joint design. 1.Bolt Bonnet Type. The valve body designed according to this connection form is connected with the valve cover by bolts. The use of a wound gasket seal has the advantage of facilitating maintenance during use; 2...

Model:Z541Y-1500LB-10″-WC6 1500 LB Pressure Seal Gate Valve is mainly used in the pipeline of the fire station in a variety of systems, cut off or connected piping media. Applicable medium: water, steam and other non corrosive media. Compared to the power station valves and other valve products is characterized by high temperature and high pressure, the unique self seal design, the higher the pressure, sealing more reliable. Due to the special properties of technical characteristics, conditions of formation of the products can not be replaced by other product characteristics. Compared to the power station valves and other valve products is characterized by high temperature and high pressure, if only from the pressure than the common valve low, simple from the temperature than was lower than the common valve. Due to the special properties of technical characteristics, conditions of formation of the products can not be replace...

900LB High Pressure Seal Bonnet Gate Valve,40 Inch,WCB Body,Butt Weld End Model:Z560Y-900LB-40″ The 900LB High Pressure Seal Bonnet Gate Valve is mainly used as an opening and closing device on the water and steam pipelines for cutting or connecting the medium in the pipeline. It should be fully open or fully closed during use and cannot be used as a regulating valve. Working principle of power station gate valve: Turn the hand wheel or stem nut clockwise, the valve stem drives the gate down, so that the sealing surface is matched, the channel is cut, that is, it is closed; otherwise, it is open. 900LB High Pressure Seal Bonnet Gate Valve features: 1. Pressure self-tightening seal is adopted, and the two ends of the valve body branch are welded. 2. The valve seat and valve sealing surface are made of cobalt-based hard alloy plasma spray welding, which has good wear resistance and scratch resistance. 3. The valve stem is treated by corrosion-resistant nitriding, which has go...
