Double Flange Butterfly Valve

 

Double Flange Butterfly Valve

Flange Butterfly Valve description

Low head loss.

Vulcanized seat that avoids the contact between fluid and cast iron, avoiding corrosion and damages.

100% water tight.

Bidirectional flow.

Polished disc borders to avoid damage in the seat.

No gaskets needed for installation.

Working temperature between -10ºC and 90ºC.

KXC Double flange butterfly valve used for regulation and flow sectioning in water supply facilities, plumbing, irrigation, etc.

It has low head loss due to a hydrodynamic design of the disc, it is 100% water tight and need no gaskets to be installed.

Types of Metal Seat Gate Valves

Image
According to the sealing surface configuration, it can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into: single gate, double gate and elastic gate; parallel gate valve can be divided into single gate Plate type and double gate type. Divided according to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve. 【 Resilient Seat Gate Valve 】 For industrial valves, the opening and closing parts of soft-sealed gate valves are gates. The movement direction of the gates is perpendicular to the direction of the fluid. The gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled. [Principle of Resilient Seat] The resilient seat l gate valve is divided into two types: bright-stem resilient seat gate valve and dark-stem resilient seat gate valve. Usually there is a trapezoidal thread on the lifting rod, through the nut in the middle of the gate and the gui...

What is a knife gate valve?

Image
Knife gate valves are designed primarily for on/off and isolation service in systems with high suspended solids content. Knife gate valves are particularly suitable for handling slurry, viscous, corrosive and abrasive media. These valves have minimal pressure drop in the fully open position, they are easy to start, they have a relatively low weight and are cost effective.   When are knife gate valves used? Knife gate valves are commonly used in mining , power plants and in the paper, chemical and food industries. Knife gate valves have the advantage of being very compact due to the linear movement of the closing flap (the plate that stops the flow of fluid in the closed position). The knife gate valve is primarily a globe valve, although it can also be used as a control valve when the flapper valve is in the partially open position. Knife gate valves can be used for fluids containing solid particles, such as waste water or sludge. Generally, knife gate valves are designed to seal o...

Midline (concentric) The structural characteristics of the midline Centerline (concentric) The structural feature of the centerline is that the shaft center of the valve stem , the center of the gate, and the center of the body are in the same position. The structure is simple and the manufacturing is convenient. Common rubber linings belong to this category. The disadvantage is that the gate and the valve seat are always in a state of squeezing and scratching, large resistance distance, and fast wear. In order to overcome squeezing, scratching, and to ensure the sealing performance, the valve seat is basically made of elastic materials such as rubber, but the sealing material is also limited by temperature in use, which is why people traditionally think that it is not resistant to high temperatures. Applicable to the pipelines of petroleum, chemical, food, medicine, paper, water and electricity, ships, water supply, drainage, smelting and energy, etc., and can be used in a variety of ...
