When would you use ductile iron sleeved plug valves?
Ductile iron sleeved plug valves are a great option for homes that need to be very energy efficient. These valves are manufactured with an iron sleeve that conducts heat with water. This means that these valves are less likely to cause a home’s pipes to expand or contract, which could cause fitting problems or even damage to pipes. This is especially important for older homes where the pipes beneath the floor may be at risk of expansion.

What is the purpose of stainless steel non lubricated plug valves?
The purpose of Ductile iron sleeved plug valves is to reduce the amount of maintenance needed on a system. Because there is no lubricant to wear down over time, stainless steel plug valves are less likely to require replacement. Stainless steel non lubricated plug valves require occasional maintenance, including cleaning and rinsing the interior components and changing the O-rings that may have become dry over time. In addition to shortening maintenance intervals, non-lubricated plugs are less susceptible to corrosion. Stainless steel is more resistant to corrosion than many other materials, which makes it an especially good choice for passive water systems.
ASTM a351 cf8m non lubricated plug valves are applied in low pressure lines. because can quickly corrode and catch dust because of the high friction
What is a carbon steel jacketed sleeved plug valve made of?
A Carbon steel jacketed sleeved plug valve is manufactured from low-alloy carbon steel wrapped with PVC. With its low carbon content and high hardness, carbon steel is an excellent material for valve construction. The PVC jacket serves to insulate the Astm a351 cf8m non lubricated plug valves from the water, protecting it from corrosion caused by contact with other materials.

How do I identify an ASTM a351 cf8m non lubricated plug valve?
The most obvious way to tell if a plug valve is made from ASTM a351 cf8m stainless steel is to look for the CF8M designation on the Cast iron ggg40 non lubricated plug valves. Other valves can usually be identified by the shape, size, and color of the markings. If you are unsure, you can also consult a valve identification guide or contact the manufacturer. ASTM a351 cf8m is a non-lubricated plug valve.

Does a stainless steel sleeved plug valve have a flow direction?
No, a Stainless steel sleeved plug valve has a fixed flow direction. It is available in two sizes, and the flow direction of the larger one will be marked. The flow from two inlets will be combined and directed to the outlet. However, with equal or reverse pressures, if the plug valve is open, there can be backflow. If the valve is automated to act based on pressure, this backflow can be eliminated. In principle, there is no restriction on the flow direction of the valve.
