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.\n\u003c\/p\u003e\n\u003cp\u003e\n  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.\n\u003c\/p\u003e\n\n\u003ch3\u003eTrue Union Design for Easy Inline Maintenance \u0026amp; Servicing\u003c\/h3\u003e\n\u003cp\u003e\n  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 \u003cstrong\u003eTrue Union (Double Union)\u003c\/strong\u003e 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.\n\u003c\/p\u003e\n\n\u003ch3\u003eHigh-Integrity PPH Material Qualities \u0026amp; Standards\u003c\/h3\u003e\n\u003cp\u003e\n  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 \u003cstrong\u003eANSI SCH80\u003c\/strong\u003e for heavy-duty wall profiles and \u003cstrong\u003eGB\/T 18742.2\u003c\/strong\u003e for polypropylene piping systems.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this PPH ball valve fully compatible with standard Schedule 80 pipelines?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes.
