Gas ball valve F-M type G61 butterfly
The gas ball valve with butterfly handle GW-GZ type G61 is a compact shut-off element for domestic and light commercial gas installations. Designed for DN20 systems with a 3/4" connection, it provides precise control of gas flow in boilers, heaters or other gas appliances.
The nominal pressure rating MOP5 (5 bar) suits typical gas networks, while the T2 working temperature range from -20°C to 60°C supports stable operation in unheated rooms and standard indoor conditions. The nickel-free design reduces the risk of allergic reactions and fits projects where contact with nickel must be avoided.
The body and ball made of brass offer high mechanical strength and resistance to corrosion, and PTFE ball seals contribute to smooth operation over time. A double NBR72 O-ring on the stem enhances tightness and durability of the shut-off function. The nut–nipple connection simplifies installation in existing gas valve setups, and the butterfly handle gives convenient access even in confined spaces.
This DN20 gas ball valve is a reliable choice for installers looking for a robust gas shut-off valve and a practical alternative to a traditional gas tap in modern gas installations.
