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, […]

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 […]

The API600 trim chart specifications are designed for API600 gate valves. For API603 gate valves as well as globe valves and check valves, the same trim numbers are more loosely applied (Trim Chart not referenced in latest API603 Standard). Obviously, in regard to globe and check valve, the hardness differentials shown on the disc and […]

Spring Return Handle provides unassisted opening or closing of manually operated quarter turn valves. The model 71 and S7 Spring Return Handle for example, driven by a powerful, completely enclosed torsion spring, automatically returns the valve to the desired fully-open or fully-closed position when released. Automatic valve repositioning is a convenience and safety feature for […]

Many manufacturers and operators in the oil and gas industry have leakage problems with elastomer seals, especially when a drop in pressure takes place. This primarily occurs in sealings which create a barrier against gaseous media if highly pressurised gas falls to a very low pressure level within a very short period of time. The […]

Fugitive Emission, Firesafe, AGA approved, etc.

Early last century there was Cameron (USA) (which the Russian’s copied!) and then WKM (USA), then along came Grove (USA), in Japan along came Kitz, then KTM and IKS (WKM under license). In Europe there was Borsig (Germany) and TK (Scotland), not long after in the early 70’s came BC Richards Australia (who also made […]

Cast steel API 600/ API 603, mass produced Wedge Gate valves and inline, cast globe valves will not necessarily always function properly on a 90 or 45 degree angle which is common practice in refineries.

In floating ball valves 316 (CF8M ball) trim is the standard because under 150mm there is only a minimal cost advantage using ENP trim in 150/300 class as the ball wall thickness is not large and the balls are mass produced keeping the costs down. However, in the trunnion mounted arena 316 trim is utilised […]
