The safety valve is an automatic discharging pressure unit for pressured equipment, containers or pipe roads. When the protected pressure rises over the permitted value the valve will automatically start to discharge superfluity medium and prevent the system pressure keeping on rising. When the system pressure reduces to a regulated value, the valve will be able to automatically shut and make sure the system in general operation. How to choose the safety valve correctly will be concerned to the users economic benefit and the safe for operators and equipment. types are used for the equipment and pipeline of the quality with corrode gas medium what the working temperature are less than 200℃. Take for extra pressure protection devices.

VigorPetro"s Surface Safety Valve is hydrauliclly or pneumatic actuated gate valvedesigned to close upon loss of control line pressure. The valve is used to quickly shut in the well in the event of a leak to, overpressure or failure of any of the downstream well test equipment.

The valve is used in conjunction with an emergency shut down system (ESD) and normally installed upstream of the choke manifold. The valve is remotely operated either manually by push button or automatically triggered by high/low pressure pilots. When a remote station is activated the emergency shut down panel acts as a receiver for the air signal. The unit translates this signal into a hydraulic response which bleeds the control line pressure off of the actuator and closes the fail closed valve.

Our SSV mainly includes Hydrualic Safety Valve, Pneumatic Diaphragm Safety Valve and Pneumatic Piston Safety Valve, which are suitable for all kinds of environment.

The Pneumatic safety valve is mainly used on the wellhead X-mas tree of ocean, offshore platform or onshore, whose function is when fire hazard or abnormal high or low pressure happened, it can close the safety valves automatically according to set procedure to ensure the wellhead safety.

Pressure relief valves protect vessels and piping systems from over pressure. Relief valves begin to open as the pressure increases past the set pressure, but require about 10% over pressure to completely open. As the pressure drops, the valves begin to close, shutting fully after dropping sufficiently below the set pressure. Safety relief valves and pop-off valves open completely when the set pressure is reached.

Care should be taken in selecting a relief valve that will pass enough flow to relieve the system from over pressure. Refer to ASME and API codes when selecting safety relief valves, particularly in steam, air, hot water, and chemical applications.

American Petroleum Institute. The American Petroleum Institute is the national trade association for the oil and natural gas industry. The API develops standards for valves used in different types of service. Here are the most common API standards that apply to valves:

American National Standards Institute. ANSI provides valve standards in the form of temperature and pressure ratings, which are based on the valve’s housing material. The ANSI pressure class ratings are: 150#, 300#, 400#, 600#, 900#, 1500#, and 2500#.

American Society of Mechanical Engineers. The ASME publishes the Boiler and Pressure Vessel Code, which establishes safety regulations for boilers and pressure vessels. The sections most relevant to valve applications are:Section I (Power Boilers)andSection VIII (Pressure Vessels).

Pressure above the Maximum Allowable Working Pressure (MAWP) of a vessel during discharge through a pressure relief device. Accumulation is expressed either in pounds per square inch or as a percentage.Cf.overpressure.Accumulation = overpressure when the set pressure of the valve equals the MAWP of the vessel.

An indication of valve leakage. No valve is 100% bubble tight. Instead, this designation indicates that a valve is not leaking above the maximum allowable amount for the valve classification. Also calledzero leakage.

An abnormal rapid up-and-down movement of a valve disk on the valve seat, often due to insufficient blowdown. Chatter can damage the valve seat.Cf.flutter.

The process of inserting a device into a pipe to seal it. Line stopping allows valves to be serviced and replaced on pressurized systems under full operating conditions.

Pressure above the set pressure of the relief valve. Overpressure is expressed either in pounds per square inch or as a percentage.Cf.accumulation.Overpressure = accumulation when the set pressure of the valve equals the MAWP of the vessel.

A valve that opens when pressure in a vessel exceeds a specified value. The valve closes when the vessel returns to normal pressure conditions. The termpressure relief valveis commonly used as a blanket description forsafety valves,relief valves, andsafety relief valves.

A pressure relief valve that opens when the static upstream pressure exceeds the opening pressure. A relief valve opens in proportion to the increase in pressure. Normally used with incompressible fluids.

A pressure relief valve that opens in response to static upstream pressure. A safety valve opens rapidly and fully, with a popping action. Normally used with compressible fluids.

Maintaining safe operating conditions can be challenging in deep-set or deepwater, high-pressure/high-temperature (HP/HT) wells. The REACH™ subsurface safety valve from Baker Hughes provides an answer, with fail-safe operation in a wide range of deep-set completions that require low operating pressures due to control system limitations.

REACH safety valves are designed to provide reliable sealing in deep, HP/HT wells. They can be set up to 20,000 ft (6,096 m) below sea level and withstand temperatures up to 400°F (205°C) and pressures up to 20,000 psi (1,379 bar).

REACH safety valves are V1 validated and have undergone the stringent prototype testing per API SPEC 14A, Specification for Subsurface Safety Valve Equipment, Twelfth Edition. Our safety valve specialists have continuously modified the design to accommodate the new V1 validation specifications while progressively exceeding the requirements set forth by API.

REACH valves rely on field-proven, heavy-sprung closure technology to ensure fail-safe-closed operation. Because tubing pressure is isolated from the control system, the valve can open at much lower operating pressures, reducing the cost of umbilicals in some applications.

The valve’s unique activation system requires lower valve operating pressures than previous safety valve designs by eliminating the need to overcome tubing pressure, making the valve ideal for applications with opening pressure limitations including: subsea completions, high-pressure wells, and fields where the rig site and other control facilities may have supply pressure limitations.

REACH valves incorporate several proven features from other safety valve designs, including flapper closure technology, RBT housing thread technology, dynamic seal technology, and debris exclusion geometries—all of which help deliver integrated functionality and dependability.

To ensure long term reliability, the valve is also offered with a reinforced dynamic seal configuration, upgraded dynamic seal materials, internal alignment enhancements, and an enhanced scraper ring to minimize debris. Because the REACH valve does not utilize gas springs, the operating seals and gland do not experience pressure reversals, making them ideal for your critical deepwater HP/HT applications
