Product Description
Metal Seat Cast Steel Trunnion Mounted Ball ValvesCHQDV'S metal seat ball valves are widely used in gas process or transportation industry for conventional on-off, emergency shut off and quick opening and controlling the flow. Top flange is designed per ISO5211 for easy amount various type of actuator.Features
Full port or reduce port
Fire safe design
Blowout-proof stem
Anti-static
ISO 5211 top flange
High Temperature Service
General soft seat ball valves working temperature limited up to 400℉
but metal-seat ball valves are guranteed for a maximum service temperature of 800℉.
Low Pressure Reliable Sealing
Rigen's metal-seat ball valves adopt seat spring structure,which can push upstream set tightly against the ball valve surface creating a reliable sealing even if extremely low pressure
Pressure Test
Metal-seat ball valve maximum allowable seat leakage:
Air:ANSI/FC170-2 Class V
Absolute Fire Safe Guarantee
Chqdv's metal-seated ball valves are absolute fire safe design.Metal to metal is designed between ball and seat or body&bonnet even if high temperature environments to reach fire-safe purpose.In addition,other sealing components such as stem packing can also reach fire-safe function and prevent external leakage.So all parts of the valve will not be damaged by high temperature service.
Blow-out Proof Stem&Anti-static Device
As general ball valves,metal seated ball valve are provided with blow-out proof stem &anti-static device
