Self Relieving vs Double Piston Effect Seals on Ball Valves
December 20th, 2017 by Amanda Schumann
API6D trunnion mounted ball valves with single piston effect seats (SPE) are designed to automatically release cavity over-pressure into the pipeline automatically using “self relieving seats”. Since body cavity and pipeline are isolated in the fully open and fully closed position, pressure trapped in the body cavity may be different than pressure in the line. […]

EMERGENCY SEALANT INJECTION ON TRUNNION MOUNTED BALL VALVES
November 8th, 2017 by Amanda Schumann
Be careful with trunnion mounted ball valves 100mm (4”) and under and in reduced bore 150mm (6”) and under as many manufacturers cannot put a sealant injection directly onto each seat such as in the photo shown above (RHS). They can only fit a sealant injection to the middle of the body (photo LHS). Consequently […]

API6D, Testing Procedure & Double Block & Bleed versus Double Isolation & Bleed
September 13th, 2017 by Amanda Schumann
The API6D test for a factory tested ball valve in regard to seat leakage only requires seat leakage to pass test on the second seat on the other end of the valve in both directions. There is not a mandatory double block and bleed cavity drain test requirement unless especially requested by the customer. Consequently, […]
Differencies between ISO 15848 and TA-Luft
September 6th, 2017 by Amanda Schumann
TA-Luft TA-Luft only deals with stem sealing area. Also, no third party witness is needed. The TA-Luft test qualifies only a “high-quality sealing system”. TA-Luft is considered to be complied with if metal bellows with a safety energised packing or similar sealing systems are used; as per VDI 2440. TA-Luft does not specify the number […]
