I AM INTERESTED IN DOUBLE BLOCK BLEED VALVE
![1 double block – whitford xylan – 02101c](https://combet-valves.com/wp-content/uploads/1-double-block-whitford-xylan-02101c-2.jpg)
Whitford Xylan coating
Valve completely internal and external xylan coated which can extend the life by twice that of traditional valve paints.
![2 double block – hot rolled – 000b15](https://combet-valves.com/wp-content/uploads/2-double-block-hot-rolled-000b15-2.jpg)
Hot rolled solid bar body
26% Higher tensile strength
37% Higher fatigue strength
And produces less waste than a casted product.
![3 double block – cross section – 040b12](https://combet-valves.com/wp-content/uploads/3-double-block-cross-section-040b12-3.jpg)
cross section 5x larger
Combet floating ball valve seat design
is up to 5X larger than competing trunnion designs.
![4 double block – metal to metal – 000a12](https://combet-valves.com/wp-content/uploads/4-double-block-metal-to-metal-000a12-2.jpg)
Metal-to-metal sealing system
Primary Metal-To-Metal sealing makes Firesafe Design inherent.
Elastomer O-rings are captured in the o-ring grooves in the Bonnet,
Retainer and both sides of the valve.
![5 multiple – multiple bearings – 1- 01080f](https://combet-valves.com/wp-content/uploads/5-multiple-multiple-bearings-1-01080f-3.jpg)
multiple bearing surfaces
Used to offset the friction that contributes to over-all valve torque. Bonnet employs a self lubricating bearing to reduce torque.
![6 double block – unique seat – 050d19](https://combet-valves.com/wp-content/uploads/6-double-block-unique-seat-050d19-2.jpg)
Valve bore sizes
are designed to closely match standard pipe schedules specified by ASME to optimize the valve flow coefficient
![6 2 double block – unique seat – 01121e](https://combet-valves.com/wp-content/uploads/6-2-double-block-unique-seat-01121e-2.jpg)
L-Seal design
allows pressure to pass from the upstream side of the valve and seal bubble-tight on the downstream side of the valve.

combet floating
ball valve seat design
Large Ball to Seat interface to evenly distribute torque
and to tolerate unprocessed produced fluid media.
Up to 50% reduction
in the size of an API 6D valve
Up to 40% weight
of an API 6D ball valve
