Globe valves 65 v es Flange connection PN 10/16, SDNR Options: - Drain plug - Indicator - Other flange drilling Globe valves bronze (RG5) Type : 50-SD Flange connection PN 10/16, SDNR Suitable for: Sea water, fresh water and waste water. * Specifications Type : 50-SD Material : Bronze G-CuSn5ZnPb (RG5) Pressure rating : PN 10/16 Bonnet : G valves in some late model medium-duty and heavy-duty truck engines (to prevent premature valve erosion), but is not commonly used in performance exhaust valves. For most performance applications, the exhaust valve material of choice is 21-4N - or titanium. Titanium is often viewed as the ultimate valve alloy material because it is about 40 There are different ball valve types with various designs for specific uses, but basic ball valve parts are the same among them. Different ball valves can be classified based on different features such as: Number of Ports: Ball valves can be easily categorized based on the number of ports. A standard ball valve type has 2 ports (1 inlet and 1 Offshore standard, DNVGL-OS-D101 - Edition July 2015 Page 3 Marine and machinery systems and equipment DNV GL AS CHANGES - CURRENT Changes - current General RISING STEM TYPE GATE VALVE Reffer to JIS F7427 (F7367) 32A Standard Standard WVBCFSJ10 Reffer to JIS F7427 (F7368) 25 4.10 CAST BRONZE RISING STEM TYPE GATE VALVE FOR MARINE USE 4-19 16 290 125 9.71 1.0 0.2 1.4 Maximum working pressure Mpa 0.5 0.2 0.7 W V B C F S J CAST BRONZE RISING STEM TYPE GATE VALVE FOR MARINE USE - 5K, 10K Applicable welded bonnet type. Standard gasket design for bolted-bonnet valves is spiral wound type up to class ASME 1500. Ring Joint gaskets are standard for ASME 2500 and above. SPW/RJ are available on request for all pressure classes as option. Flanged valves are provided with ˜ anges integral with the body forgings. APPLICABLE STANDARDS Marine Boilers Book pdf. Description :- Marine Boilers provides the information required by marine engineers taking the Steam Paper, Class Two, for the Certificate of Competency for Marine Engineering Officers of the Department of Transport on boilers and related equipment as used at sea. Much of the information is given in the form of R. Arztmann: Operation and maintenance of different valve types _ 8 4.4 Poppet valve Disassembly, cleaning and checks as mentioned above under 4.2. Using special tools does the rework of the seats. This job is easier than it is for the plate and ring type valves. Wear in the bores for the poppets of the valve guard can limit its lifetime. The valve is named as the shape of the disk in the form of ball or spherical. 4. Plug Valve : Plug valve is an rotational type of valve used for start or stop or throttling of fluid flow. Petcock is the simplest form of plug valve. The body of plug valve is machined to obtain tapered or cylindrical form of plug. Gate, globe, diaphragm, pinch, and lift check valves are linear motion valves. Linear valves are of two types: rising stem (multi-turn) and axial. In both valve types, the flow obstructer moves linearly but there are wide differences in construction and operation. Below is a breakdown of seven kinds commonly used in the oil and gas industry. 1. Gate Valves. The gate valve may be the m
