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.

U-packing seals are a type of sealing solution that is commonly used in hydraulic and pneumatic systems to prevent leakage of fluids or gases. These seals are typically made from rubber or other elastomeric materials and are designed to fit into a groove or recess in the housing of the system is sealed. The u-packing seals consist of a packing made of rubber combined with a housing made of Teflon vulcanized. The rubber is the main pressure-bearing element, and the interference of the inner and outer diameters ensures that the housing is tight against the sealing contact surface, thus realizing the sealing principle. The U-shaped cross-section of the seal gives it its name, as it resembles the letter "U". The seal is typically installed with the open end of the U facing the pressure being sealed, which allows the pressure to force the lips of the U against the surface being sealed, creating a tight seal. U-packing seals are known for their ability to handle high pressures and provide reliable sealing performance over a wide range of temperatures and operating conditions. They are commonly used in medium-pressure valves with good leakproof performance. As a low-cost valve stem seal is widely used in the petrochemical industry.

Description Peek (Polyether ether ketone) is a high-performance thermoplastic material that is known for its excellent mechanical, thermal, and chemical properties. Peek is often used in industrial applications where high temperature, chemical resistance, and mechanical strength are required. A peek seat is a component that is often used in valve applications. It is a seat made from peek material that is used to provide a tight seal between two components. A peek o-ring, on the other hand, is a type of o-ring made from peek material. O-rings are mechanical seals that are used to prevent the leakage of gases or liquids. Peek o-rings are known for their excellent chemical resistance, high-temperature resistance, and low friction coefficient. They are often used in applications where standard elastomeric o-rings would not be suitable due to their inferior properties. Sealing principle: The peek seat is a V-spring that is used as a force-applying element. The seal housing made of PTFE composite or peek has a good leak and crush resistance. As a seat seal ring, it is widely used in high-pressure valves, usually, the inner and outer seal rings of the seat are used together.
