Stainless Steel One Piece Ball Valve

The stainless steel one piece ball valve from manufacturer Joepai is a switch used to cut off and connect the medium in the pipeline. It can not only easily control the on/off and flow of the pipeline, but also has a beautiful effect. The valve with a working pressure of 1,000PSI(WOG), and made from carbon steel WCB, stainless steel (CF8,CF8M), lockable lever to prevent misoperation.

Product Highlights

1. Heavy-Duty One Piece Investment Cast Body

Manufactured by advanced silica sol investment casting technology imported from Taiwan. Integrated monolithic body eliminates middle leakage paths. Thickened heavy-duty body plus CNC precision machining ensures precise thread profile, no deformation or seepage under long-term high pressure, sturdy and long service life.

2. Lockable Safety Handle to Prevent Misoperation

Built-in 90° stop positioning mechanism, lockable device optional to fix open/closed status, ideal for unattended pipeline systems and maintenance work. Clear ON/OFF marking on lever, quarter-turn quick operation, smooth opening & closing without resistance.

3. Blowout-Proof Stem with Reverse Sealing

Bottom-loaded stem with back-seal structure prevents stem ejection under abnormal cavity pressure surge, greatly reducing high-pressure leakage risks. Elastic PTFE seat provides tight zero-leak sealing performance even after thousands of switch cycles.

4. Wide Temperature & Multi-Media Compatibility

Working temperature: -29℃ ~ 180℃ (PTFE seat); -29℃ ~ 300℃ (PPL seat). Applicable for pipelines PN1.0~4.0MPa. Stainless steel body resists corrosion, compatible with water, steam, oil, nitric acid, acetic acid and various industrial fluids.

Applications

Ideal shut-off valve for industrial piping, heating & water supply, chemical fluid delivery, oil & gas, wastewater treatment and mechanical equipment lines. Less leakage points for easy maintenance and reliable long-term flow control.

Same type of ball valve,why choose ours?

Our stainless steel one piece ball valve has more advantages than the market:

Precision That Fits Your System

At Joepai, every thread is cut with purpose. Our precision lathe work ensures accurate tooth pitch and consistent surface finish—not just for show, but for reliable sealing, smooth actuation, and trouble-free installation.

Finished Right, Out of the Box

While many market valves leave the factory with rough lathe marks and unfinished cavities, Joepai delivers truly finished products. Our secondary finishing process eliminates burrs and irregularities, so you get a ready-to-install component that protects your seals and extends system life.

Thicker Wall. Longer Life.

We engineer our one-piece stainless steel ball valves with a reinforced, thickened body—designed to handle higher pressures, heavier cycles, and harsher environments. The market standard? Lightweight, thin-walled construction that saves material at the expense of reliability. The result is a valve that works—until it doesn't, and all too soon.

Joepai Durability = Lower Total Cost

A thinner valve may cost less today. But when it fails prematurely, you pay for downtime, replacement labor, and lost production. Joepai valves are built to outlast—delivering years of dependable service, not months of compromise.
