What is a butterfly valve?
Butterfly valves have a wide range of uses in the water, wastewater, fire protection, and gas supply industries, as well as in the chemical and oil industries, fuel handling systems, and power production. The basic construction, which does not take up a lot of space, as well as the lightweight and reduced cost when compared to other valve designs, are some of the benefits of this type of valve.
A butterfly valve is a shut-off valve with a straightforward design. The disc stops the valve hole in the closed position, while the disc is spun to enable flow in the open position. The butterfly valve provides for rapid opening and closing by turning a quarter turn from fully open to fully closed, or the other way around.
An acentric or concentric butterfly valve is the most frequent form of butterfly valve arrangement. The stem of this sort of butterfly valve travels along the middle line of the disc in the center of the pipe bore, and the seat is the inside diameter of the valve's body. This no offset valve arrangement is also known as a resilient-seated valve because the seal's dependability is dependent on the flexibility of the seat rubber when the flow is closed. The disc first interacts with the seat at roughly 85�° for a 90�° revolution in this sort of valve. In low-pressure applications, concentric butterfly valves are commonly utilized.
The concentric butterfly valve is a flow control mechanism that controls the flow medium in the system with a rotary disc. The disc stays in the passage, but it provides very little resistance to the flow due to its thinness. The design of concentric butterfly valves is relatively straightforward. The basic components of a concentric butterfly valve are the body, seal, disc, and stem. A disc is positioned in the middle of the connecting pipe, and a stem is connected to the actuator or handle on the exterior of the valve in the typical butterfly valve. The disc is perpendicular to the flow when the valve is closed, and the seat of the valve is closed.

Surface safety valves (SSVs) are essential safety devices used in oil and gas production systems to prevent the uncontrolled release of hydrocarbons from the wellhead. They are designed to automatically shut off the flow of oil and gas in the event of an emergency, such as a blowout or equipment failure.
SSVs are typically installed on the wellhead, and they are activated by a remote control system located at the surface. When the control system detects a potential safety hazard, it sends a signal to the SSV to close, which stops the flow of oil and gas from the well. This helps to prevent the release of hydrocarbons into the environment, which can have serious environmental and safety consequences.
Design Details
SSVs come in a variety of designs, but they all share the same basic components, including a valve body, actuator, and control system. The valve body is the main component of the SSV, and it contains a gate or ball valve that can be opened or closed to control the flow of oil and gas. The actuator is responsible for moving the valve, and it is typically powered by hydraulic, pneumatic, or electric systems. The control system monitors the wellhead for potential safety hazards and sends signals to the actuator to activate the SSV when necessary.
The surface safety valve is an important component of wellhead production. When high pressure enters the drive, the bottom spring will open the valve. Through console operation, the spring on the relief valve will automatically push the stem to close the valve, thus ensuring the safety of the production. assembled safety valve with consideration of optimal safety and economics. The available safety valve sizes are from 1-13/16" through to 7-1/16", with pressure ratings from 2000psi to 20000psi.
