NPT check valve: reliable anti backflow, suitable for harsh working conditions

Zhejiang Yongyuan Valve Co., Ltd. was established in 1967 and is a leading enterprise in valve intelligent manufacturing with over 50 years of experience in the entire industry chain. Our company has obtained international authoritative certifications such as API 6D certification from the American Petroleum Institute, API607/6FA fire certification, T Ü V SIL functional safety certification, etc.

In industries such as petroleum, chemical, power, and water treatment, NPT check valves have become an ideal choice for pipeline systems due to their American standard taper pipe thread (NPT) connection and excellent anti backflow performance. The NPT check valve ensures one-way flow of the medium through the automatic opening and closing of the valve disc, avoiding backflow pollution or equipment damage, especially suitable for high-pressure and highly corrosive environments.

Product highlights of NPT check valves:

NPT thread seal - tapered thread design, easy installation and strong sealing, effectively preventing leakage.

High pressure and corrosion resistance - high-quality materials such as stainless steel and carbon steel are available, suitable for harsh media such as acid, alkali, and high temperature.

Low maintenance design - simple structure, sensitive opening and closing, reducing failure rate and maintenance costs.

Instructions for using NPT check valve:

During installation, it is necessary to confirm the thread rotation direction (usually right-hand) and wrap sealing tape to ensure airtightness.

NPT check valves can be installed horizontally or vertically, but it is necessary to ensure that the direction of valve disc movement is consistent with gravity (such as when installed vertically, the flow direction of the medium is upward).

Regularly inspect the wear of the valve disc and sealing surface of the NPT check valve to avoid the accumulation of particles that may affect its closure.
