Stream Flo offers full bore crown gate valves with the ability to regenerate without dismantling from the pipeline along with long life seats. Their use is very wide ranging from: wellheads, Fracking wellheads, ESD systems, choke reduction valves and kill manifolds. Valves can be equipped with one or two-way pneumatic or hydraulic actuators with manual control and protection system with closed or open safety position.
Types of produced valves:
Crown gate valve model A
Available from 2 1/16” to 4 1/16”
Pressure from 2000 psi to 5000 psi
Flow direction – unidirectional
Cast body
Expanding gate design
Mechanical seal
Stem seal can be supplemented
Gate death space is isolated from the flow
Crown gate valve Model B
Available from 5 1/8” to 6 3/8”
Pressure from 2000 psi to 5000 psi
Flow direction – bidirectional
Cast body
Split gate design
Parallel gate valves are equipped with springs which are responsible for self-cleaning the valve and its sealing even at low pressure
Stem seal can be supplemented
Rear seal allows seal or stem seal to be replaced
Crown gate valve model Sl-2
Available from 2 1/16” to 9”
Pressure from 3000 psi to 15000 psi
Flow direction – bidirectional
Forged body
Slab gate design
Patented two-piece seal system
No access ports on the body
Pin securing the stem from excessive torque
Rear seal allows seal or stem seal to be replaced
Certified as SSV
Certificate API 6FA
Structures of manufactured crown gate valves:
Parallel expanging gate
Thanks to this solution, we obtain an extremely high mechanical force of the sealing in the seat which acts simultaneously on both sides.
Two segment gate
The gate body is constructed in such a way as to allow passage through the pipe to the second gate.
Solid slab gate
It uses a bidirectional construction with a floating slab that moves parallel to the seat.
Split gate
This bidirectional valve is fitted with a metal-to-metal seal between the slider and the seat and the seat and body. The seal is reinforced by an auto-seal system.
Kill mainfold
Depending on needs it contains all the necessary equipment and connections for the application.
