What is semi Lug butterfly valve?
Similar as wafer type except a pair of the thread bolt hole in way of the upper and lower sides for easy maintenance of adjacent pipe. Easy handling and light weight.
What type of valve is butterfly valve?
quarter-turn valves
A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The “butterfly” is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway.
What is the difference between lug type and wafer type butterfly valve?
Lug type valve as the name suggests has lugs that are used to mount the valve to lugs that are attached the flanges on then ends of sections of pipe so that each length of pipe can be removed and replaced independently. Wafer type valves don’t have attachment lugs, though them may have alignment lugs.
What is Wafer Check Valve?
Wafer check valves have a solid thermoplastic body with a very thin “wafer” profile that makes them an ideal check valve for applications that require valves with short takeout lengths. Wafer check valves are used in applications where it is essential to ensure fluid flow passes in only one direction.
What is a globe valve used for?
Globe valves, so-called because of their outside shape, are widely used in plant piping. They are suitable for manual and automatic operation. Unlike the gate valve, globe valve can be used for regulating flow or pressures as well as complete shutoff of flow.
What is lug type valve?
Lug type valve as the name suggests has lugs that are used to mount the valve to lugs that are attached the flanges on then ends of sections of pipe so that each length of pipe can be removed and replaced independently. Typically there are 8 or 12 lugs where 4 or 6 lugs are used to connect the each pipe section.
What is a lug check valve?
The DUO CHECK valve LUG type covers the bolt along the entire length of the body. LUG type valves are supplied in scallop to keep the weight as low as possible, thereby minimizing the cost. LUG type valves are supplied with straight-through bores according to API-594. Note: 1.
What is a lug butterfly valve?
Lug Butterfly Valve. The lug version of the butterfly valve’s design is similar to a 3-piece ball valve in that one end of the line can be taken off without having an effect on the opposing side.

What are valve lifters?
Valve lifters are cylindrical parts inside of your engine, about the size of a finger. They often have a tiny hole inside of them which allows oil to lubricate the inside of the cylinder.
