2. Separator (oil production) - Wikipedia

   en.wikipedia.org/wiki/Separator_(oil_production)

   The valves required for oil and gas separators are oil discharge control valve, water-discharge control valve (three-phase operation), drain valves, block valves, pressure relief valves, and emergency shutdown valves (ESD). ESD valves typically stay in open position for months or years awaiting a command signal to operate.

3. Block and bleed manifold - Wikipedia

   en.wikipedia.org/wiki/Block_and_bleed_manifold

   Two block valves and a bleed valve are as a unit, or manifold, to be installed for positive isolation. Used for critical process service, DBB valves are for high pressure systems or toxic/hazardous fluid processes. Applications that use DBB valves include instrument drain, chemical injection connection, chemical seal isolation, and gauge isolation.

   Double check valve; Duckbill valve; Fill and drain valve: a valve used in space and missile industry which achieves extremely tight leakage, while providing redundant inhibits against external leakage [1] Flapper valve; Flow divider valve: a valve providing a plurality of output flows from a single fluid source [2]

5. Oil filter - Wikipedia

   en.wikipedia.org/wiki/Oil_filter

   An oil filter is a filter designed to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Their chief use is in internal-combustion engines for motor vehicles (both on- and off-road ), powered aircraft , railway locomotives, ships and boats, and static engines such as generators and pumps.

6. Valve guide - Wikipedia

   en.wikipedia.org/wiki/Valve_guide

   The upper part of the valve stem, within the rocker box, is lubricated by oil. If this oil travels unchecked along the valve stem, engine HC emissions will become excessive. To control this, an elastomeric seal is fitted over the top of the valve guide. These may wear or stiffen with age, so are usually replaced whenever valves are removed for ...

7. Oil pump (internal combustion engine) - Wikipedia

   en.wikipedia.org/wiki/Oil_pump_(internal...

   Too much oil pressure can create unnecessary work for the engine and even add air into the system. To ensure that the oil pressure does not exceed the rated maximum, once pressure exceeds a preset limit a spring-loaded pressure relief valve dumps excess pressure either to the suction side of the pump, or directly back to the oil pan or tank.
