SELF-PIERCING VALVE PV-1

The Self-Piercing Valve PV-1 (Reference: 080901) by Multitanks represents a major innovation in the field of quick-connect fittings. This specialized valve allows you to instantly create a tap point on your existing installations, without service interruption or complex disassembly. Developed to meet the needs of demanding professionals, it guarantees a secure and durable installation on tubes with diameters of 1/4, 5/16 and 3/8 inches.

Applications and decisive advantages

The PV-1 valve excels in multiple usage contexts. In industrial maintenance, it allows quick addition of measurement or sampling points without stopping production. For refrigeration installations, it offers the possibility to connect gauges or diagnostic equipment directly to existing circuits. HVAC technicians appreciate its ability to create temporary or permanent branches without prior system evacuation.

Its self-piercing mechanism eliminates leak risks during installation, while its robust design ensures long service life even under severe conditions. Homeowners also use it for their automatic irrigation projects or specialized equipment connections.

Technology and technical compatibility

The PV-1 valve integrates a precision piercing mechanism that cleanly penetrates the tube wall without creating burrs or weak points. Its high-quality machined brass body resists corrosion and chemical agents commonly used in industry. The high-performance elastomer seal maintains constant pressure even after numerous opening-closing cycles.

Its 1/4 NPT or BSP threaded outlet (depending on model) universally adapts to standard market fittings. The valve accepts copper, aluminum and certain technical plastic tubes, with extended compatibility to refrigerants, compressed air, water and numerous non-corrosive hydraulic fluids.

Simplified installation and commissioning

Installing the PV-1 valve requires no specialized tools. Simply position the valve on the clean and degreased tube, then gradually tighten the fixing nut until the mechanism pierces the wall. A tactile indicator confirms complete perforation. The valve remains automatically closed until voluntary opening of the internal needle.

For maintenance, periodically check seal tightness and proper functioning of the opening mechanism. In case of prolonged non-use, keep the valve closed to preserve seals. Disassembly, if necessary, is performed after complete circuit depressurization.
