For procurement managers and plant engineers who need reliable, code-compliant valves — avoid mismatched connections, leakage, and costly downtime with our factory-direct valve fitting solutions.
📑 Contents
Every year, procurement teams and plant engineers lose thousands of dollars not because of valve function, but because of mismatched valve fitting types. Whether you are sourcing for a water treatment plant, an oil & gas pipeline, or a commercial HVAC system, the connection method — flanged, threaded, or welded — must match your piping standard, pressure class, and installation environment.
Re-ordering the correct valve fitting type can add 3–6 weeks to your project timeline and up to 18% in expedite fees.
Threaded connections installed on high-pressure steam lines (above 300 psi) have a 23% higher failure rate than butt-weld joints.
Using the wrong flange facing (RF vs. RTJ) can result in failed inspections and fines up to $50k per incident in regulated industries.
More than 40% of procurement managers report sitting on excess stock because valve fitting types did not match site requirements.
The result? Budget overruns, safety incidents, and strained supplier relationships. You need a partner who understands valve fitting types in detail and can deliver exactly what your project demands — on time, every time.
At Ningjin Thriveon Valve Co., Ltd., we manufacture and supply every major valve fitting type used in industrial, commercial, and municipal systems. Our product line covers flanged gate valves, threaded globe valves, butt-weld check valves, wafer butterfly valves, lug-style ball valves, Y‑type strainers, foot valves, and stainless steel valves with threaded, butt-weld, or socket-weld ends.
Flanged connections use bolted flanges with gaskets, making them ideal for pipelines that require frequent maintenance or high-pressure integrity. Available in ANSI 150/300/600, DIN PN10/16/25, and JIS 10K/20K with raised-face (RF), ring-type joint (RTJ), or flat-face (FF) finishes.
Applications: Water treatment, oil refineries, chemical processing, fire protection systems.
Threaded-end valves are the most common valve fitting type for small-bore piping (≤ 2"). Available in NPT (National Pipe Taper) for North American markets and BSP (British Standard Pipe) for European and Asian projects. Our threaded valves feature precision-machined threads for leak-free sealing without sealant tape in most applications.
types of valves and fittings valves types plumbing valve types
Applications: Plumbing, compressed air, instrumentation, low-pressure steam.
For high-temperature, high-pressure, or hazardous fluid systems, welded-end valves provide the strongest possible connection. Butt-weld ends are used for larger pipes (≥ 3"), while socket-weld ends are preferred for smaller pipes (≤ 2") in critical services. We comply with ASME B16.25 (BW) and ASME B16.11 (SW) standards.
Applications: Power generation, petrochemical, offshore platforms, high-pressure steam.
Wafer-style butterfly and check valves fit between two pipe flanges, reducing weight and footprint. Lug-style butterfly valves allow single-side isolation for maintenance. Both types are available with EPDM, NBR, Viton, or PTFE seats.
Applications: HVAC, water distribution, food & beverage, marine systems.

Quick answers to the most common procurement and engineering questions.
Flanged connections use bolted flanges with a gasket — ideal for large diameters (≥ 2″) and high-pressure systems. They allow easy disassembly for maintenance. Threaded connections (NPT or BSP) screw directly into the pipe — best for small diameters (≤ 2″) and low‑ to medium‑pressure applications where space is limited.
For high-temperature steam (above 400 °F / 200 °C), butt-weld (BW) or socket-weld (SW) ends are recommended. These welded joints eliminate leak paths and maintain structural integrity under thermal cycling. Flanged connections with spiral-wound gaskets can also work, but require careful torque management.
Yes, provided the valves carry NSF/ANSI 61 certification for drinking water. Our threaded ball valves and check valves are available with NSF 61 compliance on request. We supply both NPT and BSP threads to match local plumbing codes.
Raised Face (RF) is the most common for ANSI 150–600. Flat Face (FF) is used for cast iron or low-pressure systems. Ring Type Joint (RTJ) is required for high-pressure (ANSI 600+) or high-temperature services. We can supply all three; just specify your standard when ordering.
Yes — we specialize in OEM and ODM projects. Our engineering team can design valves with custom end connections, special materials (Duplex, Super Duplex, Monel), bore sizes, and actuation mounts. Minimum order quantity varies by complexity, but we are flexible for both small and large volumes.
Standard flanged gate valves (ANSI 150/300) in sizes DN50–DN300 are typically shipped within 15–25 working days from order confirmation. Larger diameters or special materials (e.g., Duplex) may require 30–40 days. We offer express production for urgent projects.
Yes, we offer free samples for qualified procurement teams and engineering firms. You only pay the shipping cost. Contact us with your required valve fitting type, size, pressure class, and quantity, and we will arrange a sample for testing.
Our technical sales team can help you select the optimal connection based on your pipe material, pressure/temperature rating, fluid type, and installation environment. Simply send us your piping class specification or P&ID, and we will recommend the right valve fitting type with a detailed quotation.
