Bellows-Sealed Valves, B Series (MS-01-22;rev N;en-US;Catalog)
www.swagelok.comW designates welded body-to-bellows seal. BRW series valves are not recommended for shutoff above 600°F (315°C). Ratings apply to manual valves and to valves with 5 series pneumatic actuators. For actuator ratings, see page 8. For more information about pressure ratings of valves with tube fitting end connections, see Swagelok Tubing Data, MS ...
627 Series Pressure Reducing Regulators - Emerson Electric
www.emerson.comPressure is measured under the diaphragm through the 1/4 NPT downstream control line connection (Figure 2). Type 627BM: Direct-operated pressure reducing regulator with a balanced port and a stem seal between the body outlet pressure and diaphragm case. Pressure is measured under the diaphragm through the 1/4 NPT downstream control line connection.

If a second compression test is performed shortly thereafter, and the new reading is much higher, it would be the ring seal that is problematic, whereas if the compression test pressure observed remains low, it is a valve sealing (or more rarely head gasket, or breakthrough piston
BASIC OPERATION AND FUNCTION OF CONTROL VALVES
www.controlglobal.comvalves. liquid pressure recovery factor: The ratio (FL) of the valve flow coefficient (Cv) based on the pressure drop at the vena contracta, to the usual valve flow coefficient (Cv) which is based on the overall pressure drop across the valve in non-vaporizing liquid service. These coefficients compare with the orifice metering

OVERPRESSUREPROTECTION Blowout plugis comprised of a rubber plug on the rear which functions as a relief valve by unseating and venting the gage interior when over pressure reaches approximately 25 psig (1.7 bar). To provide a free path for pressure relief, there are four
