Gas ball valve GW-GW type G61 butterfly
The gas ball valve with butterfly handle GW-GW type G61 is a compact shut-off valve for domestic and light commercial gas installations. With a nominal diameter DN20 and 3/4" female–female connection, it fits standard gas pipework and works well as a main or sectional gas shut-off point.
The valve is designed for gas media and operates at a nominal pressure up to MOP5 (5 bar), so it suits typical building gas systems. The T2 working temperature range from -20°C to 60°C supports stable performance both in unheated technical rooms and in warmer indoor spaces. The butterfly handle offers precise, quick operation, useful during maintenance or emergency shut-off.
The body and ball are made of durable brass, resistant to wear in long-term service, while PTFE ball seals contribute to smooth rotation and tight closure. The stem uses a double NBR70 O-ring, which reduces the risk of leakage around the spindle. The nickel-free design is an advantage wherever contact with nickel coatings is not desired.
The nut-to-nut connection simplifies installation in existing gas lines and helps keep the layout compact. This DN20 gas ball valve is a practical choice for installers and investors looking for a reliable gas shut-off valve with robust materials and user-friendly operation.
