GGS-QBG Mobile

Structural Features

• Equipped with GGS-QBG gas booster, it can directly increase medium-pressure gas to high pressure, ensuring on-site Safety Valve Calibration with unmatched precision.
• This equipment does not require electricity, and the boosting and calibration systems are integrated. The calibration table and boosting table combine into a high-pressure mobile unit—ideal for Safety Valve Calibration—or can be used separately for effortless transport and setup.
• Equipped with a hydraulic lifting work vehicle, it can lift the table to an ideal height, which
  is convenient for transportation and on-site operations.
• Equipped with a special aluminium alloy tool box, it is convenient to bring tools and
  calibration table accessories to the site for calibration.
• The clamping force of 1-9 tons can be adjusted stepless according to different calibers
  and pressures.
• Dual precision pressure gauge display, more accurate calibration.
• The safety protection baffle with calibration high-pressure safety valve greatly improves
  the safety performance.
• The pneumatic clamping structure is clean, fast, has a low failure rate, and is easy to
  operate.
• The operating valve uses high-quality military valves.
• The equipment is equipped with a safety valve with an automatic opening protection
  device for clamping overpressure.
• The equipment frame and table are made of stainless steel.

Technical Parameters

1. Calibration range: DN20~200mm
2. Maximum calibration pressure: 32MPa (320 bars)
3. This equipment adopts an adjustable clamping force structure, with a clamping force of 1 to 9 tons and stepless adjustment. When adjusted to the corresponding clamping pressure, the maximum pressure that can be calibrated for each gear diameter is shown in the table below:
   Note: This check seat is an adjustable clamping force structure, which must be adjusted according to the diameter and cracking pressure of the safety valve to be calibrated. Otherwise, the clamping pressure is too high, which will damage the safety valve to be calibrated; the clamping pressure is too low, and the sealing requirements cannot be met. For details, see the above table.
   
4. Calibration accuracy: ±0.4%
5. The calibration medium is nitrogen or clean compressed air, and the medium source is prepared by the user. This equipment should not be used to test other valves.
