When an angle valve is used as a shut-off valve for residential plumbing fixtures, it is called an angle stop valve, or simply an angle stop.

An angle needle valve’s inlet and exhaust apertures are angled at 90 °. Particular applications are more suitable for the angle needle valve due to its reduced pressure loss. When space is limited or the fluid must change direction, the angled body of these valves can assist. Instead of an in-line flow, these needle valves reverse the flow from the inlet by 90 degrees. While the operational principle remains unchanged, the 90-degree angle facilitates enhanced system integration.
Systems of processing plants, refineries, and LPG that are challenging to deactivate due to solid particles, corrosion, and particulate substances.
Standard Test: Seat and packing leakage of each valve is evaluated using nitrogen at 1000 psi, with a maximum allowable leak rate of 0.1 standard cm3/min.
Hydro Test: conducted at 1.5 times the working pressure using purified water. On request, temperature and helium leak evaluations are provided at a maximum working pressure of 10,000 psi (700 bar).
Material, pressure, dimension, and temperature are the primary attributes and application prerequisites when choosing a needle valve.
The particular application determines the material of the needle valve enclosure. Brass and stainless steel are the most frequently used materials for valve housings due to their broad spectrum of chemical resistance; however, alternative materials are also accessible to cater to specific applications.
Angle needle valves made of stainless steel are chemically resistant to all media. The material is resilient and resistant to high pressures and temperatures. Unless the stainless steel is subjected to continuous exposure to salinity, it remains compatible with aggressive and corrosive environments such as seawater; otherwise, corrosion may occur.
The port and orifice dimensions of needle valves are extremely diverse. Ends on the connection terminals may be either male or female. The National Pipe Thread (NPT), the British Standard Pipe (BSP), and the metric system (ISO standards) are frequently employed thread standards. The most prevalent needle valve dimensions are 2 to 12 mm (1/8″ to 2″). Ensuring the proper port and orifice dimensions promotes efficient flow and system operation, with fewer erosion and leakage chances.
Comprehending the pressure application specifications in a given system is crucial to opt for the appropriate angle needle valve. At 100°F, robust needle valves can withstand pressures between 275 and 413 bar or 4,000 to 5,000 psi (equivalent to 275 to 413 bar). For high-pressure hydraulic applications, for instance, high-performance valves are accessible; these valves have a maximum pressure capacity of 10,000 psi (689 bar) at 100°F (38°C). The vacuum needle configuration is resistant to low pressure.
Angle needle valves are appropriate for applications involving high or low temperatures. Specify the packing/sealing material and valve housing accordingly, particularly for extreme temperatures, to ensure they can withstand the specifications. For a temperature range of -65°F to 450°F (-54°C to 232°C), the two most prevalent sealing materials are PTFE (Teflon) and PEEK (Polyether Ether Ketone), which provide enhanced resistance to temperatures up to 600°F (315 °C).
There is normally a sequence of processes involved in the manufacturing process of needle valves. The first thing that must be done is to choose the materials relevant to the valve components, considering the requirements. Stainless steel, brass, and other alloys are examples of materials that are often used. Machines are then used to manufacture the different components of the needle valve, including the valve body, stem, seat, and other internal pieces. These components are created by machining the materials that have been selected. Machining with precision is very necessary to obtain extremely tight tolerances and a clean surface finish.
After completing the machining process, the various components are combined to form the full needle valve. This process ensures that everything is precisely aligned and secure. Following the completion of the assembly process, the needle valve is subjected to tightness testing to ensure there are no leaks and that the valve can efficiently regulate fluid flow.
Polishing and coating are two examples of surface finishes often applied to the outside surfaces of the needle valve. These treatments improve the valve’s overall look and increase its resistance to corrosion. Procedures for quality control are carried out at different stages of the production process to guarantee that the valve satisfies the industry standards and requirements. Measurements such as pressure testing, dimensional inspections, and other quality assurance procedures are included here.
It is highly suitable for demanding oil and gas installations, such as processing plants and refineries, hydraulic applications, water treatment facilities, and power plants.
There are a variety of operational challenges and safety concerns that might arise as a result of a needle valve that has failed. Leakage, uneven flow control, operating difficulties, corrosion and erosion, sticking or jamming, damage to internal components, and possible disturbances to the system are some common issues connected with a needle valve that is not performing to its full capacity. Typically, to solve these concerns, it is required to either replace the malfunctioning needle valve with a new one or undertake repairs to restore the needle valve’s initial performance. It is vital to perform routine maintenance on the needle valves and replace them at the appropriate time to avoid these issues and ensure the system continues unassisted functioning.
