S.H PPH True Union Ball Valve | S5 1.25MPa Chemical-Grade Hot-Melt Socket Fusion Double Union Valve (20mm - 110mm)

Xieyu S.H Premium PPH True Union Ball Valves (S5 / 1.25MPa)

Control, shut off, and maintain your industrial, chemical, and fluid-treatment pipelines smoothly with our premium Xieyu S.H PPH true union ball valves, available at Atradesen.com. Manufactured by Xieyu (S.H / HIEH), a globally recognized leader in high-performance thermoplastic flow control, these heavy-duty PPH (Polypropylene Homopolymer) double union valves are engineered to withstand continuous operating pressures up to 1.25 MPa (181 PSI) and temperatures from -20°C to 100°C.

Featuring standard parallel socket depths, a high-contrast orange T-handle, and double-union locking nuts, this true union valve series is highly compatible with industrial chemical pipelines, acid pickling loops, electroplating lines, waste gas scrubbers, waste acid recovery, and wastewater treatment.

True Union Design for Easy Inline Maintenance & Servicing

In continuous industrial pipeline manifolds, standard inline valves require you to cut the pipeline if internal seals wear out, need cleaning, or become jammed by crystallization. Our specialized True Union (Double Union) valve resolves this maintenance challenge: simply unscrew the two union nuts on either side of the valve body by hand. This allows you to slide out the central valve block for direct cleaning, ball inspection, or gasket replacement without having to cut, re-weld, or compromise the main piping line on either end.

High-Integrity PPH Material Qualities & Standards

Molded from high-purity Homopolymer Polypropylene, these S5-rated valves offer superior chemical resistance to highly corrosive media, organic solvents, strong alkalis, and mineral acids. This series conforms to strict international standards, including ANSI SCH80 for heavy-duty wall profiles and GB/T 18742.2 for polypropylene piping systems. PPH is also non-toxic and odorless, making these valves completely safe for drinking water pipelines, pharmaceutical loops, and food processing lines.

⚠️ Sizing & Socket Fusion Guidelines

Nominal pipe dimensions are based on standard outer diameters. Please measure your pipe outer diameter (OD) before placing your order:

• Female Socket End (ID): The designated nominal size corresponds directly to the outer diameter (OD) of your pipe: 20mm (DN15), 25mm (DN20), 32mm (DN25), 40mm (DN32), 50mm (DN40), 63mm (DN50), 75mm (DN65), 90mm (DN80), and 110mm (DN100).
• Connection Methods: Requires standard socket fusion hot-melt welding connection. Ensure both pipe ends and internal sockets are cleaned and dried before heating to secure optimal molecular fusion. Alternatively, they can be welded using PPH plastic welding rods.

Frequently Asked Questions (FAQ)

Q: What is the main operational benefit of a True Union (Double Union) Ball Valve?

A: In chemical processing or aquatic filtration sumps, pipes are permanently welded. If a valve leaks or clogs, replacing a standard socket valve requires cutting the pipe and installing new couplings. With a True Union design, you simply spin off the locking nuts on both sides, pull out the central valve cartridge to clean or change gaskets, and slide it back in. No pipe-cutting is required.

Q: Is this PPH ball valve fully compatible with standard Schedule 80 pipelines?

A: Yes. As molded clearly on the valve body, this PPH ball valve is designed to ANSI SCH80 (Schedule 80) dimensions, which guarantees standard wall thickness and pressure ratings required in chemical processing industries.
