|| Gate Valve
Parallel expanding gate gives positive seal
across both seats .
A double row roller thrust bearing on the
stem makes operation easy . even under
full pressure .
Upper and lower roller thrust bearings are
used to minimize torque and are isolated
from pressure of medium .
The full bore through conduit design
minimize pressure drop ,eliminating
The seal faces are protected from in the
open and closed positions for long life.
Non-rising stem gate valve.
Bolted bonnet .
Hand wheel operated .
Basic Design and Test API-6A
Working Pressure ( Psi ) 3000
Main Nominal Size 4-1/16
Product Specification Level PSL2
Performance Requirement Level PR2
Material Class EE
Working Temperature -50°F to
250°F ( L ̃ U )
Flanged RTJ ( R37)
|| Adjustable choke valve ( External
Both sleeves in the external sliding and
seat nozzle are made of solid Tungsten
Carbide , which are abrasion and erosion
With the pressure – balancing bores in the external sliding sleeve , the stem will face
the minimum load form downstream
With bean size indicator on the stem , the
throttle bore can be observed .
Maximum orifice (3") bore.
The stem will be locked when tighten to the
wing nut position so as to assure the
selected flow rate maintained .
