Matherne Choke Pressure System | 6 in Dial, up to 15,000 psi (20,000 psi Deboosted)
The Matherne Choke Pressure System gives the crew a quick, clear reading of choke pressure to help maintain well control. It combines a 6 in pressure indicator with a standard 50 ft high-pressure hose and works with a diaphragm protector, piston isolator or 4:1 debooster that keeps well fluids out of the system. Standard capacities run to 15,000 psi straight pressure, or 20,000 psi with a debooster, and the dial can be supplied with fine line increments for choke work.
Key features
- Fluid-filled indicator to reduce shock, vibration and corrosion
- 360° dial calibration for maximum pointer travel
- Adjustable damper for steady pointer movement
- Box mount or panel mount; suits choke consoles, panels or stand-alone use
- 2 in Fig. 1502 hammer unions as standard, or 2 in Fig. 2202 for H2S service
