Application of Wedge Gate Valve SS
Wedge gate valves are a type of gate valve that uses a sliding gate or wedge to control fluid flow. They are commonly used in various industries including oil and gas, chemical, and petrochemical.
This type of gate valve can be made from a variety of materials, including stainless steel. Stainless steel is a popular choice for wedge gate valves because of its resistance to corrosion, high temperatures, and high pressures.
Stainless steel wedge gate valves are often used in applications where the fluid being controlled is corrosive or contains abrasive particles. They are also used in applications where the valve will be exposed to high temperatures or pressures.
Wedge gate valves typically have a simple design, with few moving parts, which makes them reliable and easy to maintain. They are often used in isolation applications, where the valve is either fully open or fully closed, rather than in applications where the flow rate needs to be controlled.
Request a Z40W or Z41W Quotation
The listed FOB prices are indicative. A current quotation should match the model, material configuration, quantity and delivery requirements. For a Z40W enquiry, request a price for that configuration rather than using the Z41W list as a substitute.
Ask Farpro about your stainless steel gate valves with the model, required size, quantity and destination. For a replacement, an existing nameplate photo and connection details give us a useful starting point.
If the job calls for remote isolation, the Z941W electric flanged gate valve is an existing option to compare with the manual arrangements shown here.
