PIG LAUNCHING & RECEIVING SEQUENCE

LAUNCHING

Ensure the valve is in the closed position. Vent the body cavity with the bleed fitting on the Entry Cap.
After valve is vented, the body fittings may be opened to drain or flush the valve.

After venting the body cavity pressure, remove the entry cap and insert the pig through the opening.
CAUTION: When unscrewing, if gas or liquids start to emerge STOP! Screw Entry Cap back on and verify Step 1.

Stand facing the valve stem to insert the Pig.
NOTE:

Install Pig conical side DOWN if flow is from left to right.
Install Pig conical side UP if flow is from right to left.

Before re-installing the Entry Cap on the valve, inspect seal integrity. Then, after ensuring the bleed fitting and all body fittings are closed - open the valve to launch the pig.

RECEIVING

Verify valve is installed as a receiver pig valve with the catcher plate downstream of the flow.

When the pig is received, close the valve. Vent the body cavity chamber with the bleed fitting on the entry cap. After the valve is vented, the body fittings may be opened to drain or flush the valve, if necessary.

Inspect all seals on the Entry Cap to ensure seal integrity. Reinstall the Entry Cap on the valve. Ensure the bleed fitting and all body fittings are closed. Open valve.

NOTE: For easier operation, apply anti-seize to the ACME threads of the Entry Cap.
CAUTION: Always dispose of hazardous materials appropriately.

CAM VALVE TECHNOLOGY

THE CAM VALVES SYSTEM UTILIZES A SIDE ENTRY SYSTEM OF SAFETY LATCHES FOR EASE OF ENTRY IN THE SAFEST POSSIBLE MANNER.

A completely revolutionary valve with patent pending technology that improves the accessibility to the central components for easy maintenance and repair. Our pig valve comes with several customization options to fit costumer needs.

Heavy duty Catcher Plates are constructed for longevity. The ability to vary the flow pattern through the Plate allows for optimal performance in a variety of services including liquids and solids containing streams.

TAKE A LOOK INSIDE

Forged Body - Provides structural integrity.
Ball - Maximized sealing surface for reliable isolation.
Catcher Plate - Prevents overtravel of Pig and contains it in the bore of Ball
Seat - Provides a perfect seal.
Body Seal - Prevents leakage to atmosphere. Variety of materials available to suit application.
Stem Seal - Protects against leakage to atmosphere.
Trunnion Bearing - Helps ensure consistent operating torque.
Stem - High strength for maximum safety.
ISO Mounting Bracket - Standardizes Gear and Actuator mounting.
Safety Valve - Prevents opening of Closure without proper cavity and Ball bore pressure relief.
Ball Bore and Cavity Relief - Allows pressure contained in Ball bore to be relieved in order for Closure to be opened.

FUGITIVE EMISSION TESTING

HELPING TO REDUCE EMISSIONS ON A GLOBAL SCALE

Why use Helium in Fugitive Emissions Testing?\It provides the most sensitive and up-to-date method of testing.Helium is a safe and inert gas.
Helium is a very searching gas and therefore readily penetratesminute leaks.
It’s a proven technology that simulates live conditions Nocontamination of the atmosphere due to helium being non-toxic, non-hazardous and non-destructive Fugitive Emissions Testing Capabilities:

Production test: Normally carried out at ambient temperature and involves cycling the component during the test (in accordance to ISO 15848-2 or Shell SPE 77/312).
Proof test: Temperatures are elevated and reduced for type test approval (in accordance with ISO 15848-1 or Shell 77/300).
