  1. Butterfly Valves – Configurable to Meet Your Demands Proline Valves is a highly configurable of butterfly valves designed to meet all of your specific demands. Our butterfly valves can be configured for manual operation, or for use with electric or pneumatIc actuators. Our electric actuators are available with a weatherproof or explosion-proof housing option and are offered in a variety of supply voltages.

  2. What is a Butterfly Valve? A butterfly valve is a quarter-turn valve that initiates throttling and flow control of fluids. Given its name, you can easily visualize a thin metal disc that “flutters” about a fixed axis (stem assembly). The opening and closing mechanism allows and restricts the flow of a medium between an upstream and downstream pipe

  3. Advantages • Here are some of the advantages of • butterfly valves compared with other valve types. • Lightweight and compact • Easy to install • Low-pressure loss • Low maintenance • Simple, rapid operation

  4. Disadvantages The disc can interrupt flow even when it is open Not recommended for high differential pressures

  5. Regulating Fluid Flow In butterfly valves, fluid flow constriction and control is easily done by just turning the valve handle. As it is a regulating valve, it controls the flow rate of system through the help of actuators. Basically, when a flow monitor senses that a set parameter (differential pressure) has been reached, it will signal the valve actuator to close or open the valve. To control a regulating valve remotely, it must have a flow controller which automatically communicates with the valve mechanism based on the flow rate.

  6. High-Performance Valves for Heavy-duty industry applications • For large and heavy-duty applications such as in oil and gas industries or high-pressure controls, high-quality and high performance butterfly valves are needed. These high-grade valves are certified and quality tested to meet quality demands and international standards.

  7. Types of Butterfly Valves • Butterfly valves can be categorized in many types. The most known classification is by end-connection type (lug or wafer). But it can also be classified according to seat design Wafer Type Ends – have a flexible seal that protects the system from backflows which occurs when bi-directional pressure occurs Lug Type Ends – has threaded “lugs” or inserts around its circumference that permit for bolt passages

  8. Valve Actuation • Electric-Operated Valve – use an electric actuator for operating the valve in an open and close position. • Pneumatically-operated valves – Pneumatic actuators are used to operate these types of valves for shut-off pipelines. • Hydraulic Piston – These types of valves are used for applications requiring huge impacts or force for opening and closing the valve. • Manual or handwheel operation – These types of valves are manually operated through a hand-wheel or crank. Hence, they are not automatic.

  9. Installation • In order to check parts of the butterfly valve, you can be able to disassemble it in order to further inspect its parts. • Before anything, see to it that the flange and pipeline are clean from foreign materials. These can damage the seat or disc and can also cause disc to movement restrictions. • In order to easily insert the valve body, spread the flanges and align the pipe-work. With this the valve body is inserted even with no contact to pipe flanges. • Slowly open the disc. This will test if it has the right clearance form the inside of the pipes.
