MOGAS DV-4 Switching Valve
MOGAS DV-4 Switching Valve
The DV-4 switch valve features many advantages over existing ball or plug valves on the market today. Backed by innovative R&D, world renowned after sales service and a reputation for quality, the DV-4 represents product advancements in delayed coking switching operations.
Features:
- Patent-pending oversized outlet •
- Reduces backpressure and coke accumulation in heater by maintaining 90 to 100% flowrate during switching (compared to less than competitor’s 60%)
- Semi-trunnion (sleeve and seat ring supports ball)
- Maintains alignment and equalizes wiping forces
- Prevents uneven seat loading and leakage
- Lowers steam consumption by sealing body cavity
- Keeps process media out of body cavity
- Reduces torque
- Belleville springs with seat rings
- Lowers steam consumption by eliminating bellow spring purge inlets
- Eliminates prone-to-fouling bellow springs
- Optimized purge system
- Simplifies installation using manifolds for two purge inlets and two purge outlets – one packing purge – three body purges – two drain purges
- Increases switching reliability via body cavity flushing; evacuates body cavity media before and after switching using purge outlets
- Lowers steam consumption; appreciable steam consumption only during switching and body cavity flushing
- Integral flange connections
- Prevents lock-up of the valve due to pipe loads (especially at warm up) because the seats are not coupled to the end flanges
- Patent-pending bonnet
- Reduces area for coke build-up
- Simplifies repair and trim replacement via true top entry design
- Patent-pending two-piece stem adaptor
- Prevents stem and actuator damage using sacrificial pins
- Dual stem guides
- Prevents misalignment and packing leaks due to side loads
- Extended mounting bracket
- Allows room for ease of packing maintenance
- Prevents electric motor and gear from high temperature exposure
- External stem extension rod
- Indicates true flow and ball bore position
- Verifies flow direction with actuator removed
