More Great Information on Butterfly Valve:
The Purpose of a Dump Valve For a Turbo Charged Engine by James Heron
Dump valves are designed to release unused boost pressure when lifting off the throttle of a turbo car. When a turbo car accelerates it produces a positive pressure referred to as boost. When you come off the accelerator the throttle butterfly is closed and this boost has no escape route so backs up through the intercooler causing back pressure on the turbo which tries to stop if from spinning. Fitting a dump valve gives this boost the all important escape route it needs. As a result turbo lag will be reduced resulting in faster pick up between gear changes. For a ?whooshh style? noise go for an atmospheric dump valve. For silent operation go for recirculating.
A dump valve, or commonly known as a blow-off valve, is a pressure release system in turbocharged engines. It fits between the compressor outlet and the throttle, and it reduces the wear on the turbocharger, as well as the engine, by relieving the damaging effects of the compressor. It allows compressed air to either re-circulate or vent to atmosphere by bypassing the pressurized air on a closed throttle.
In order to install a dump valve, the vehicle must have a turbocharger or supercharger. Blow off valve kits are available for many models, such as Audi, Ford, Mitsubishi, Nissan, Subaru, and Volkswagen. Car manufacturers usually fit a dump valve for emission purposes, as well as fuel economy and drivability. Most people who install a dump valve aftermarket do so for a boost level that is higher than the standard, for better throttle response, and of course, to make the blow-off hiss or whoosh noise.
There are two specific brands of dump valves. Bailey Motorsport offers a piston design dump valve, which has faster reaction time, increased boost capability, and it can work on cars with airflow meters. They sell either the single piston or twin piston Bailey dump valve if you are a noise lover. If you prefer a more quiet boost, they offer the piston-type recirculating dump valve. The prices range from $83.00 to $118.00, depending upon the style you prefer.
Forge Motorsport offers a variety of dump valves, as well. Forge maintains that their valves are designed and built with the intention of venting 100% of residual charge air to the atmosphere. They carry single piston and dual piston valves, as well as offering a re-circulating valve. Prices start at $138.00.
A dump valve can be fitted by several different modes. For example, a hose mount can be used, which makes it easier to replace, if necessary. A pipe mount can also be used by welding the base into position between the compressor outlet and the throttle. Vehicle specific flange adaptors are also available.
Installation of a dump valve is a personal preference. Some people, mainly car enthusiasts, love the hiss and whoosh sound made when the air vents to atmosphere. Others feel that there is no benefit to vehicle performance, and after a while, the noise becomes bothersome. Dump valves require a certain amount of maintenance, and this is another sore spot for some who do not care to spend the time under the hood, especially when they notice little performance benefit.
The main goal for installing a dump valve is to protect the turbocharger, and to date, it has not been shown to increase power. However, in some car models, an immediate change to the car can be felt, particularly when changing gears, due to the continued spinning of the turbo in closed-throttle conditions, thus enabling a quicker "full boost" to the car.
Choosing the correct dump valve is essential for the health of a high powered turbo charged car. Bailey dump valves offer quality and reliability at an affordable price.

where are the butterfly valve are used?
*A butterfly valve is a type of flow control device, typically used to regulate a fluid flowing through a section of pipe. The valve is similar in operation to a ball valve. A flat circular plate is positioned in the center of the pipe. The plate has a rod through it connected to an actuator on the outside of the valve. Rotating the actuator turns the plate either parallel or perpendicular to the flow. Unlike a ball valve, the plate is always present within the flow, therefore a pressure drop is always induced in the flow regardless of valve position.
Butterfly valve
*A butterfly valve is from a family of valves called quarter-turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the process fluid. The valve may also be opened incrementally to regulate flow.
*There are different kinds of butterfly valves, each adapted for different pressures and different usage. The resilient butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating. The high performance butterfly valve, used in slightly higher-pressure systems, features a slight offset in the way the disc is positioned, which increases the valve's sealing ability and decreases its tendency to wear. The valve best suited for high-pressure systems is the tricentric butterfly valve, which makes use of a metal seat, and is therefore able to withstand a greater amount of pressure.
*The butterfly valve has a body, a resilient seat, a butterfly disk, a stem, packing, a notched positioning plate, and an actuator. The resilient seat is under compression when it is mounted in the valve body, thus making a seal around the periphery of the disk and both upper and lower points where the stem passes through the seat. Packing is provided to form a positive seal around the stem for added protection in case the seal formed by the seat should become damaged. To close or open a butterfly valve, the actuator is turned only one quarter turn to rotate the disk from 0° to 90°. Actuators used on butterfly valves vary based on the application and size of the valve. A simple handle oriented in the same direction of the metal disc (to indicate valve position) is common. Some larger butterfly valves may have a handwheel that operates through a gearing arrangement to operate the valve. This method is used especially where space limitation prevents use of a long handle. Acuators may also be air driven or electrically operated when used as part of an automated control system.
