Description
VALVE WITH SOLID WEDGE FOR HIGH TEMPERATURE – KTN 344
The KTN 344/800 is our class 800 gate valve with socket weld ends. Made of forged A105 carbon steel. Designed to provide a good seal with hardly any pressure drop. Suitable for high pressure and high temperature service. It can be used bidirectionally. The range is from 1/2” to 2” and the maximum working pressure is 140 Bar. The working temperature range covers from -29ºC to +425ºC. The valve has seats and gate reinforced with stellite. Indicated for conducting and stopping the passage of aqueous media, oils and gas.
Features
VALVE WITH SOLID WEDGE FOR HIGH TEMPERATURE – KTN 344
Stellite seats
Stellite is an stainless steel and nickel alloy at high temperature. The seats reinforced with stellite makes them almost indestructible, extremely hard, impact resistant, heat resistant. They will hold position angle forever.
Stellited wedge
Solid wedge with best mechanical strength specially appropriate for turbulent fluid flow, the gate is lightly inclined against the flow to create an angle wedging force that helps the valve to close and also increases reliability seal at higher fluid pressure ratings.
Graphite packing
Heat resistant graphite packing that provides a tight seal on the stem when its pressured by the gland and gland flange.
Sealing parts
Heat resistant graphite gasket and stainless steel glands that provide excelent sealing between bonnet, body and stem.
F6 Stem
Non rising stem makes it more suitable for limited space installations with simple design with less parts to be exposed to the fluid decreases the risk of stem leakage.
Body and bonnet
Body and bonnet made of ASTM A105 forged carbon steel specially designed for high pressure systems at high-temperature service.
