Brass 2-way Ball Valve Tube To Tube manufacturer, supplier, and exporter in India

A Brass 2-Way Ball Valve Tube to Tube is an inline quarter-turn shutoff valve engineered with integrated double-ferrule compression tube ends on both the inlet and outlet ports. Each tube port consists of four precision components: the fitting body port with an internal beveled cone, a front ferrule, a back ferrule, and a threaded compression nut. When tightened 1-1/4 turns past finger-tight, the front ferrule is driven into the body cone to burnish a 100% metal-to-metal primary pressure seal, while the rear ferrule cams radially inward to produce a tight collet grip on the tube outer wall without flaring, soldering, or threading the tube.

Integrated double-ferrule tube ends eliminate the need for separate tube-to-male-pipe adapters, completely removing two potential leak paths per valve installation. Unlike pipe threads that rely on messy PTFE tape or chemical pastes which can shear into the fluid stream and contaminate sensitive valve seats, double-ferrule compression connections provide clean, reliable, metal-to-metal seals with exceptional resistance to vibration, pressure impulses, and thermal expansion cycles.

Pioneer Brass 2-Way Tube to Tube Ball Valves are rated up to 6,000 PSI (400 bar) in standard virgin PTFE seat configurations, and up to 500 Bar (~7,250 PSI) in high-pressure hydraulic models utilizing precision-machined Delrin (polyacetal) or PCTFE seats. All valves are engineered in strict compliance with ASME B31.3 chemical plant and petroleum refinery piping codes with a certified 4:1 hydrostatic burst safety factor.

Pioneer Brass Tube to Tube Ball Valves are fully compatible with seamless copper tubing (soft annealed or half-hard per ASTM B75/B88), seamless brass tubing (ASTM B135), and soft aluminum tubing (ASTM B210). When used with semi-rigid nylon, polyethylene (PE), polyurethane (PU), or PTFE tubing, Pioneer brass internal tube support inserts must be installed into the tube bore to prevent polymer wall creep under compression ferrule bite.

The stem is precision CNC machined from high-tensile brass with an integral enlarged lower safety collar. It is inserted into the valve body cavity from the interior before the ball and polymer seats are fitted. Even under severe internal hydrostatic pressure surges, process water hammer, or external gland packing adjustments, line pressure drives the collar tightly upward against the body shoulder recess, making stem ejection physically impossible.

The micro-ground and mirror-polished spherical brass ball floats freely between two resilient polymer seats. When the valve is closed by a 90-degree handle turn, line differential pressure pushes the sphere downstream against the resilient seat, generating an energized, airtight metal-to-polymer seal. The sealing performance complies with API 598 and BS EN 12266-1 zero-bubble leakage criteria in both flow directions.

The patented geometry of the double-ferrule system isolates the primary pressure seal at the front ferrule from mechanical line vibrations. The rear ferrule acts as an integrated vibration damper, clamping firmly around the tube circumference and dampening line harmonics before flexural fatigue stresses can reach the primary sealing surface. This ensures zero leakage on engine dynos, air compressor skid drops, and marine machinery.

Yes. Pioneer Brass 2-Way Tube to Tube Ball Valves feature an externally threaded bonnet neck supplied with a heavy brass locking panel nut. This allows rigid bulkhead installation through control cabinet fascias, instrumentation panels, and test console enclosures up to 12 mm thick without disturbing the tube connections or disassembling internal valve trim.

Every single Pioneer valve undergoes 100% individual pressure testing compliant with API 598 and BS EN 12266-1. Quality procedures include a hydrostatic shell proof test at 1.5 times maximum working pressure and an underwater pneumatic nitrogen seat test at 1,000 PSI to verify zero gas leakage. Shipments are accompanied by authentic EN 10204 Type 3.1 Mill Test Certificates detailing chemical analysis, tensile properties, and ferrule hardness validation.

To ensure a leak-tight connection: (1) Cut the tubing perfectly square (90°) using a quality tubing cutter and deburr both internal and external edges; (2) Insert the tubing cleanly through the nut and ferrules until it firmly bottoms out against the internal valve body shoulder; (3) Tighten the compression nut finger-tight; (4) Mark the nut and body with an ink pen at the 6 o'clock position; (5) Using an open-end wrench while holding the valve body with a backup wrench, rotate the nut exactly 1-1/4 turns (1.25 turns) to the 9 o'clock position for sizes 1/4″ and above (or 3/4 turn for 1/8″ sizes).
