The GE Oil & Gas Masoneilan 77000 Series High-Pressure Labyrinth Trim Control Valve provides high-pressure, compressible fluid control without the erosion, vibration, and high noise associated with conventional control valves. It is ideal for multi-phase flow applications and features an advanced energy management trim design that dissipates energy through high head loss rather than shock waves.
The valve offers smooth, stable control with a high range of 50:1 and eliminates cavitation by reducing pressure drop in smaller increments. It features wide flow paths for dirt tolerance and reliable tight shutoff meeting IEC 534-4 and ANSI/FCI 70.2 Class V requirements. The design includes optional bottom-loaded flanged or top-loaded butt-weld end connections for field maintenance flexibility.

It provides high-pressure, compressible fluid control without the erosion, vibration, and high noise associated with conventional control valves.
The multi-stage trim design reduces the pressure drop in smaller increments without allowing the local pressure at each stage to drop below the fluid vapor pressure.
Yes, wide flow paths in the trim allow for the passage of large particles entrained within the flow stream that would otherwise cause damage or loss of capacity.
