Description

VALVE WITH F316L SEATS WITH HIGH HARDNESS STELLITE – KTN 381

The KTN 381/800 is our class 800 gate valve with NPT threaded ends. Made of forged stainless steel F316L. 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.

Estelite seats
Stellite is a high temperature alloy of stainless steel and nickel. The Stellite reinforced seats are almost indestructible. Extremely hard and resistant to impacts and heat. Able to maintain the angle position forever.
Stellited wedge
Solid wedge with the best mechanical resistance especially suitable for working with turbulent fluid, the gate is slightly inclined against
flow to create an angled wedge force that assists the valve in closing and also increases sealing reliability at high pressure.
Five seal packing
Heat resistant graphite packing provides a tight seal on the stem when pressed by the stuffing box and stuffing box flange.
Insulating parts
High temperature resistant graphite gasket and stainless steel stuffing box provide an excellent seal between the bonnet, body and stem.
Stem in F316L stainless steel
Non-rising stem making it more suitable for installations in limited spaces. It offers a simple design with fewer parts exposed to the fluid which reduces the risk of stem leaks.
Body and bonnet
Body and bonnet made of forged F316L stainless steel. Specially designed for high pressure systems for high temperature service.
