Floating Ball Valve
Floating ball valves are side entry, fire safe, anti-static and locking designs. The Steel Floating Ball Valves meet API 6D, API 608, and API 598.
A floating ball valve is a ball valve with its ball floating inside the valve body. It drifts toward the downstream side and tightly pushes against the seat under the medium pressure to ensure sealing reliability. The Relia floating ball valve has a self-relieving seat that relieves pressure upstream.
The floating ball valve has a simple structure and good sealing performance, but the seat material is required to withstand the workload since the sealing pressure is borne by the seat ring.
