Screwed Bonnet Valve Female Female Npt

Screwed Bonnet Valve Female Female Npt is designed for leak free closure, regulation and management of fluids in process systems under High Pressure environment of 15000 psi . With a wide variety of port sizes, end connections, style, temperature and pressure tolerance FAV High Pressure Needle Valves 15000 psi are critical for instrumentation, fluid and process control system. They are available in NPT ,BSP ,Size 1/4″ to 1″

In the manufacture and supply of valves, fittings and industrial connectors using adapters, we are the well-known brand in the industry. We have served a wide range of industrial sectors and supplied products that meet industry standard specifications and guarantee the precise design of safeguards and systems performance. We have a wide range of products and trusted manufacturers of multiple valves who deliver reliable, high-end systems quality products. In industrial valves and fitting design we recognise the value of sustainable quality, and therefore we never compromise our quality.

We give a wide range of needle valves with rich expertise-how that are commonly used in flow measurement, especially where a constant, calibrating low flow rate, such as idle fuel flow in a carburetor, is retained for a period of time. Our valves for low torque and high tensile strength are well appreciated on the market. These are furthermore sold to consumers in the right packaging to avoid wear and tear during transport. Needle valves or shut-off valves are designed for line mounting insulation, calibration and drainage.
