This underground ball valve, DN100 PN16, is a full-bore welded-end shutoff valve with pneumatic actuator, engineered for buried pipeline service where excavation for maintenance is costly and reliability is non-negotiable. The alloy body and straight full-bore design pass the working medium without flow restriction or pressure loss, and welded connections eliminate the flanged joints that become leak points underground.
The manufacturer rates the valve for natural gas, liquid and gaseous petroleum products, water, acids and alkalis, making one valve family applicable across gas distribution, oilfield gathering and industrial pipeline networks. The pneumatic drive enables remote and automated operation — a requirement for shutoff valves integrated into SCADA-controlled networks and emergency isolation schemes.
Rated to 16 bar nominal pressure at 100 mm nominal diameter, the valve is priced around 1,500 dollars and available singly, addressing pipeline operators, gas utilities and EPC contractors building or upgrading buried infrastructure.
