  Wafer butterfly valve   is a very wide range of valve types, it has a soft seal and hard seal two types of seal.In the same caliber, hard - sealed Wafer butterfly valve price will be higher than soft - sealed Wafer butterfly valve. A variety of materials such as gray cast iron, nodular cast iron, cast steel, stainless steel, etc.And hard seal to Wafer butterfly valve material is limited, can only be cast steel or stainless steel.The reason is that two different sealing forms of butterfly valves, the use of the working condition is not the same, soft sealing can only be used for low pressure, room temperature environment.Hard seals are used in high pressure and high temperature environments. If you need the price of clamping butterfly valve, please click on the official website of XUVAL Valve online customer service to make an inquiry, tell us your working conditions and relevant parameter information of clamping butterfly valve, we will give you a reasonable price of Wafer butterfly

  Cast iron gate valves or carbon steel gate valves? This article【 XUVAL 】for you to introduce. Cast iron gate valves Cast iron gate valves are divided into gray iron gate valves and ductile iron gate valves.The valve body of gray iron gate valve is made of gray iron and its seal is copper seal.The valve body of ductile iron gate valve is made of ductile iron and sealed with rubber seal.Cast iron gate valves have two types of structure: rising stem and dark stem. Cast iron gate valves are mainly used in water system pipelines, suitable for ambient temperature and low pressure, including municipal water supply, building water supply and drainage, farmland irrigation and so on. Carbon steel gate valve Carbon steel gate valve is basically a rising stem structure, the sealing surface material is stainless steel, can be used in high temperature, high pressure environment, such as petroleum, chemical, metallurgy, energy systems and other pipelines, the use of carbon steel gate valve.

  Not only butterfly valve but also ball valve is one of our leading products.The biggest difference between the ball valve and butterfly valve is that the opening and closing parts of the butterfly valve is a plate, and the ball valve is a ball, the butterfly valve disc and the ball valve spool are around their own axis for rotation;The disc of gate valve is moved up and down along the axis;Butterfly valves and gate valves can be opened to adjust the flow;Ball valves do not facilitate this. Butterfly valve  is characterized by fast opening and closing speed, simple structure, low cost, but the tightness and pressure capacity is not good, suitable for making large diameter valves.The characteristics of ball valves are similar to gate valves, but due to the volume and open and close resistance, it is difficult to achieve large diameter. Ball valves  have a better seal than butterfly valves.Ball valve seal is by the seat of long-term extrusion on the sphere, it must wear faster than half
