Driving device for Manual Wafer Butterfly Valve

The driving device of the manual wafer butterfly valve is mainly the handwheel and the handle. For valves with little torque required for opening and closing, a manual device, handwheel or handle can be used to directly fix the valve stem or valve stem nut. The diameter of the handwheel is based on the relevant […]

Where can butterfly valves be used

The butterfly valve is a kind of valve used to control the fluid flow in the pipeline. It uses the disc-shaped butterfly plate as the opening and closing part, and rotates 0~90° reciprocatingly to realize the opening and closing of the butterfly valve. Butterfly valves are used in a wide range of applications. In general, […]

Advantages and Disadvantages of Centerline Butterfly Valves

Advantages of Centerline Butterfly Valves The centerline butterfly valve adopts the centerline sealing structure, and the centerline of the disc sealing of the butterfly valve is consistent with the centerline of the valve body and the rotation centerline of the valve stem. The upper and lower ends of the butterfly plate near the valve stem […]

Installation and operation method of manual butterfly valve

The most common driving methods for butterfly valves are manual, pneumatic, hydraulic and electric. This article mainly introduces the manual butterfly valve. Manual butterfly valve can be subdivided into handle butterfly valve and turbine butterfly valve. The two have no major impact on the installation of manual butterfly valves, and the difference lies more in […]

Stem structure and Integral Seat of centerline wafer butterfly valve

The centerline wafer butterfly valve can be divided into two types: pinless butterfly valve and pinned butterfly valve. The main difference between them is whether the valve plate and valve stem are fixed with pins. The pinned butterfly valve and the pinless butterfly valve correspond to the needs of different working conditions, and more depends […]

What are the advantages of gate valves-resilient & metal seated

The gate valve has an opening and closing gate. The movement direction of the gate is perpendicular to the direction of the fluid. 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 […]

Principle and Maintenance of Silence Check Valve

Silence check valve, also called silent check valve, muffler check valve. The principle of silent check valve: The silent check valve is an automatic valve, which realizes the opening and closing of the valve flap by relying on the pressure of the medium flow. When the medium flows through the valve body, the valve flap […]

Difference between forged valve and cast valve

What is the difference between a forged valve and a cast valve? This article will explain to you how to distinguish between forged and cast valves. forged valve: Forged valves are forged and forged, and are generally used on high-grade pipelines with relatively small diameters, generally below DN50. 1. Forging: It is a processing method […]
