Product Description

Product Description

1PC Threaded Ball Valve

The valve body is casted from a single piece of stainless steel or carbon steel, with the ball inserted from one side and then sealed by compressing the valve seat. This design offers the most compact structure, light weight, fewer leakage points, and reliable sealing. However, it typically features a reduced bore design. The valve connects to the pipeline via threads, making installation and removal easy without welding.
 

1-PC Stainless Steel Threaded Ball Valve
The valve body is made of cast stainless steel (commonly CF8/304 or CF8M/316). It offers excellent corrosion resistance and is suitable for water, steam, oil, gas, and various some corrosive media. 

1-PC Carbon Steel Threaded Ball Valve

The valve body is made of ASTM A216 WCB cast steel, whose core advantages are high strength, good temperature resistance, and low cost. It is suitable for a wide temperature range, typically from -29°C to +425°C. Within this range, it maintains good performance, especially for high-temperature media such as steam and hot oil. The casting process is mature, allowing for the manufacture of complex valve body structures.  It offers a low overall cost and high cost-effectiveness, making it an "economical and practical" choice among carbon steel valves. Its main weakness is its lack of corrosion resistance. It is not suitable for corrosive media such as acids, alkalis, and seawater. It is prone to rusting in humid atmospheres, so the valve should be protected with sufficient external paint or coating.Multiple international standard thread options are available:
• NPT: American National Pipe Thread
• BSPT(Rc): British Standard Pipe Taper thread
• BSPP(G): British Standard Pipe Parallel thread

1-PC Ball Valve with ISO 5211 Direct Mounting Pad

This valve combines three key technologies:
1. 1-PC (One-piece body): The most compact structure with fewer leakage points, usually featuring a reduced bore design, suitable for fixed installations and applications with limited space.
2. Threaded connection: Convenient for small-diameter pipes (such as DN15-DN50) and eliminates the need for welding.
3. ISO 5211 Direct Mounting Pad: This is the key to achieving automation. It is a standardized interface that allows for direct and rapid installation of pneumatic, electric, and other actuators, eliminating the need for brackets and couplings, and ensuring precise alignment of the drive shaft.

The greatest value of this combination lies in providing a compact and easy-to-install valve body with a pre-integrated interface for automation upgrades, accommodating both current manual operation and future automation modifications.

1PC Stainless Steel Guang Type Ball valve

1PC Carbon Steel Guang Type Ball Valve

1PC Ball Valve Male to Female Threaded

G-style Ball Valve,a compact one-piece threaded ball valve, commonly known as 'Guang-type' in China.This compact design of the Guang-type ball valve makes it ideal for instrument piping.

Typically 304 or 316 stainless steel, providing excellent corrosion resistance and suitable for water, steam, oil, and various corrosive media.

This valve is a Guang-type ball valve made of carbon steel. It combines the compact structure of a Guang-type ball valve with the cost-effectiveness of carbon steel. It provides sufficient mechanical strength and pressure resistance, making it suitable for most medium involving steam, hot water, etc.

This valve features a female thread at one end and a male thread at the other, allowing for direct connection to pipes with either male or female threads at both ends. This eliminates the need for an additional "male-to-female thread adapter," reducing potential leak points and simplifying the bill of materials and installation process.

One-piece hexagonal bar stock ball valve

A105 Steel hexagonal bar stock ball valve

Stainless Steel Mini Ball Valves

The one-piece hexagonal bar stock ball valve is manufactured directly from a single piece of solid hexagonal bar stock, eliminating casting or welding processes, thus achieving superior integrity and reliability. Forged or rolled bar stock, compared to cast parts, possesses higher material density, better mechanical strength, and greater impact resistance.

The A105 material ball valve with a black oxide finish combines a robust bar stock structure with cost-effective carbon steel material and practical surface corrosion protection. It is an excellent choice for applications requiring high strength, compactness, and economy, especially in dry and mild operating environments.

This type of mini ball valves are precision valves designed for low flow rates and compact spaces, widely used in instrumentation, analytical equipment, and small fluid systems. Designed specifically for small diameter pipes from 1/8" to 1", with a very compact structure to save space.These small valves often have a high pressure rating (commonly PN40/64 or higher).
