UNDERSTANDING AND RECOGNITION OF BUTTERFLY VALVE

Valve type Butterfly valve is one type of valve that is versatile, can be applied to any piping system, in industry, shipbuilding, platforms, housing and others.

In addition the butterfly valve can be installed on various media installations through it, for example by liquids, gases, mud with various levels of pressure and temperature.

At first many butterfly valves were used in installations at low pressure, but with the development of technology especially in the field of elastomer, now this type of valve can be applied to installations with high pressure.
With a working rotation angle of only 90˚, this type of valve can be operated quickly but is not capable of setting for a certain flow size. This valve is commonly referred to as a quarter turn valve.

With the channel cover material a precision disc valve is driven by an actuator shaft that is connected to the handle on the outside of the valve.
From the actuator that moves or rotates the disc can be applied with a manual, hydraulic or electric motor lever. Of course with the addition of several auxiliary equipment such as valve controls for hydraulics and gearboxes that reduce motor rotation for the type of electric motor actuator.
In the open state or the cover disk at position 0 arises the aerodynamic flow caused by the disk. Although the head loss is slightly higher than the type of valve ball valve or gate valve. In fact, the globe valve and gate valve really work freely when the valve is fully open. But the loss is lower than the globe valve type.

Various types of Butterfly valves can be used for various flow media, liquids and gases as well as rather dense materials such as mud, bulbs etc.

The pressure and temperature of the material through this valve clearly affects the material of the manufacture, making it an important consideration in the design.

TYPE - TYPE VALVE FROM THE TYPE OF BUTTERFLY VALVE

Concentric Butterfly Valve, has a strong seat with metal disks.
Doubly-eccentric Butterfly Valve, from a variety of materials used for seats and disks.
Trply-eccentric Butterfly Valve, made of hard metal / steel. Eccentric types are often used in applications that require bi-directional for example oil and gas cover, LNG / NPG, in chemical factories and shipbuilding.
Wafer style Butterfly Valve, Designed to maintain seals against bi-directional pressure differences to prevent backflow in any system that is intentionally designed for unidirectional flow.
Lug-style Butterfly Valve, with screw on both sides of the valve that allows it to be installed in a system with threaded joints or does not require a bolt nut on the flange
