Product Summary
VG10.16902 brass ball valve with female/female threaded ends.
The VG10.16902 is a brass ball valve built for drinkable water systems, piping water systems and heating systems. The body is brass, and the valve is machined and assembled with matched rubber seals so it stays leak-free at its rated working pressure. Female/female threads at both ends connect straight into standard fittings and pipes, and the compact cylindrical body keeps the footprint small in plant rooms, risers and appliance connections. The valve is offered from 1/4 inch to 4 inch, works from −20 °C to 120 °C and carries a PN40 rating — 40 bar or 580 psi — so one brass ball valve family covers both small fixture lines and larger distribution pipework.
Key Features
PN40 pressure rating
Rated PN40 — 40 bar / 580 psi working pressure. Distributors can specify one valve for demanding water flow conditions instead of stepping up to a heavier body.
−20 °C to 120 °C media range
Covered by one temperature band, cold mains water through to hot heating water, which simplifies stock keeping for wholesalers serving both circuits.
1/4 inch to 4 inch size range
A single part family from fixture isolation up to distribution lines, so an installer or OEM sources one brass ball valve range across a whole project.
Female / female threaded ends
Secure threaded connections that assemble directly with common fittings and pipes — no adapters, fewer joints and faster commissioning.
CNC machining, matched rubber seals
Precision machining plus matched seals, pressure and air tightness tested. Zero leakage at rated working pressure reduces after-sales cost for the brand owner.
Automated ball valve production
70% of output runs through automated workflows, with dedicated fully automatic ball valve lines and industrial robots that limit human error and hold quality consistent batch after batch.

Models and Options
Sizes: 1/4 inch to 4 inch within the same valve family.
Threads: standard female/female configuration, with custom thread specification available to match regional markets.
Finish and branding: surface finish options and logo engraving on request.
Wider range: the same factory supplies ball valves, gate valves, check valves, stop valves, angle valves, manifolds, mix valves, gas ball valves, float ball valves and bibcocks, so a distributor can consolidate pipeline accessories with one supplier.
Materials and Structure
The valve body is machined from brass, the material specified for this model. Internal components are precision CNC machined and assembled with matched rubber seals to hold a tight shut-off at the rated working pressure. Both ports are female threaded, which gives a symmetrical body that can be installed in either direction of the line. The compact cylindrical shape keeps the valve close to the pipe axis, which matters where space is limited — inside heat pump cabinets, riser shafts and appliance connections.
Applications
Drinkable and piping water systems: isolation on supply and riser lines in residential, commercial and institutional buildings.
Heating systems: quarter-turn isolation at heat sources and risers on two-pipe radiator circuits.
Heat pump and district heating packages: isolating the circulator or plate heat exchanger for service without draining the circuit.
Gas pipeline systems: the valve is specified by the manufacturer for water, heating and gas pipeline systems; confirm the certificate that applies to your market and model before gas duty.
Customization and OEM Supply
Thread specification, surface finish, logo engraving and packaging can be customized to regional market requirements. For private-label programmes the factory handles casting, machining, assembly and testing to the customer’s own specification, drawing and part number, including part marking and full traceability in the customer’s numbering system, dimensional inspection reports, material certificates and process capability data with each batch. Customer drawings, part numbers and brand relationships stay confidential.
