Description
STANDARD GLOBE VALVE BS 1743 – KTN 431
The KTN 431 is an updated version of the globe valve with body in cast stainless steel CF8M and classes available in 150/300/600/1500, ANSI flanges.
Thanks to the presence of molybdenum [Mo] in the alloy, we have greatly improved the corrosion resistance of the steel, while maintaining the natural mechanical strength of stainless steel at high temperatures. This alloy gives the valve the possibility of working with corrosive acids such as sulfuric, hydrochloric, phosphoric and nitric. The presence of this material is very common in the food, chemical and pharmaceutical sectors.
The pressure and temperature range: ANSI B16.34 which provides significant benefits in terms of operational safety, reliability, versatility, interoperability and regulatory compliance.
Characteristics
AUSTENITIC STAINLESS STEEL GLOBE VALVE FOR GENERAL APPLICATIONS – KTN 431
Design
Created with casting software to optimize the parameters of the manufacturing process. This software greatly minimizes the probability of casting defects such as shrinkage, porosity and cracks.
Body and bonnet
Manufacturing includes pouring of the casting to reduce internal defects in the castings, and heat treatment of the casting to improve the mechanical properties of the materials, eliminate residual stresses and improve the machinability of the metal. Our manufacturing process is fully compliant with BS 1873, the average thickness exceeds the standard by 10%.
Stem nut, packing gland and packing gland
To ensure perfect stem isolation, the stem nut D2 or BS 1873 standard bronze, bronze stem nuts have high wear and corrosion resistance. The packing is reinforced by packing gland and backseat ring made of stainless steel.
Insulating parts
Corrugated heat-resistant graphite gasket for rapid adaptability to dramatic temperature changes. Composite packing offers lower torque and better sealing performance.
Stem
Strong and rigid stainless steel stem that complies with BS 1873 standard, making it almost indestructible.
Disc
Fully adjustable disc making it ideal for improved performance and flow accuracy. Combining ASTM A29M 1020 nut and ASTM A351 CF8M disc to meet API 598 destruction test requirements.
Structural strength
The globe valve body design is engineered to withstand high pressures and temperatures, ensuring structural strength and preventing failure under demanding operating conditions.
