EFCO Booster

The air/nitrogen test pressure required for a test is provided either by a customer's pre-filled high-pressure cylinder or by an EFCO-Booster.

The EFCO booster compresses air or nitrogen up to 300 bar (4350 psi) (higher pressures available on request).

EFCO VALVE-DOC

The EFCO-VALVE-DOC is a documentation and management system for valve test benches:

  • Mobile system for recording, evaluating and documenting valve tests
  • Can be used for all existing valve test benches on the market
  • User-friendly
  • Available in many languages


The EFCO-VALVE-DOC is ready for immediate use. The software is pre-installed and configured. It only needs to be plugged in and the pressure sensors connected to the valve test bench.

The system is used to display and record:

  • Set pressure and seat leakage tests of safety valves
  • Body and seat leakage tests of shut-off valves

O-ring sealing plates

Special O-ring sealing plates made of alu/hardcoated for sealing flanged fittings.

Polyurethane sealing plates (Vulkollan)

Special sealing plates made of polyurethane for the sealing of flange fittings

Safety plugs (especially for safety valves)

For seat leakage testing of safety valves with air/nitrogen.

The plugs are inserted into the outlet of the safety valve for testing and connected to the bubble sight glass via a quick coupling.

Threaded adapter (for test pieces with threaded ends)

  • Adapter flanges with female / male thread (G or NPT)
  • Steel adapter flanges for sealing threaded fittings

Stainless steel piping and screw connections for the test system

incl. stainless steel screw connection of the high-pressure hose for external testing

Digital bubble counter

Used for automatic counting of bubbles during seat leakage testing with air/nitrogen.

Digital manometers for air/nitrogen testing/water test

Digital pressure gauge, especially suitable for the uncomplicated recording of measured values during the response pressure test of safety valves.

Protective wall

Base frame made of aluminium profiles between clamping device and control panel, equipped with clear 6mm polycarbonate panes (Makrolon).

Adapter flanges for internal sealing of shut-off valves, especially for ball valves

The adapter flanges are suitable for internal sealing of shut-off valves.

Due to this type of sealing no clamping forces act on the test specimen. Therefore, this type of sealing is best suited to receive and test ball valves in the clamping device. A prerequisite is that the valve ends are machined on the inside so that the radial seal of the adapters seals.

Quick flange lock

Quick-flange closures are used to close valves and pipelines with flanged ends without multi-fittings, nuts, blind flanges, gaskets and without additional tools.

The main components are made of aluminium and are very easy to handle due to their low dead weight. Sealing against the test piece sealing surface is achieved by an integrated O-ring. The construction absorbs the specified max. pressure load and keeps the connection between test specimen and flange seal tight via the self-locking spindle.

Manual flange cap

The flange seal is used for closing fittings with flange ends in various nominal sizes, suitable for test benches without an upper test table

Drive control

Separate control box for controlling the actuators of shut-off valves and control valves (pneumatic/electro-pneumatic).

Flow meter

Flow meter for detecting seat leakage with air or water.
