Top -X-P is light, simple,
superior performance of pressure control (¡Ó 1% accuracy),
high flow capacity and the
most reliable durability comparing with all existing same
designed type of
regulators in this industry.
Application:
For natural gas transmission and/or
distribution systems.
Also used in several other industrial processes.
For abnormal pressure protection,
Select Top -X-P + SSV ¡V IH or IPH (&
The operating principle of Top-X-P creates a pressure regulator with
extraordinary speed of response to flowing demand variations and
extremely accurate pressure adjustments, while maintaining extremely low
¡§lock-up¡¨.
LOW COST AND EASY MAINTENANCE
Less parts required,
Simplification and one-man operation
of routine maintenance,
Top entry friendly design, without
moving the valve from the Pipeline!
Just have few nuts pop-off for
maintenance.

where:
Q = Maximum regulator flow (Nm3/hr)
KG = Regulator coefficient (See table)
P1 = Regulator input pressure (bar - abs)
P2 = Regulator output pressure (bar - abs)
NOTES :
1. We
suggest that the regulator sizing calculation consider a minimum safety factor
of
20% above the calculated value.
2.
For application with other gases,
the calculated flow shall be converted to an equivalent
flow
in natural gas, using the table below:
