Be on the safe side with KSB gate valves

Gate valves from KSB for maximum safety

Alongside butterfly valves, globe valves, diaphragm valves and ball valves, gate valves form part of KSB's comprehensive valve product portfolio. Gate valves fulfil the important task of securely shutting off parts of a piping system or plant. This may be required for a multitude of reasons. Whatever the reason, KSB gate valves are reliably up to the task.

Benefits of a KSB gate valve

• Safer sealing to atmosphere by fully confined bonnet gasket and gland packing made of graphite, preventing creeping of the joint ring (PN 40)
• Additional safety and blow-out protection by screwed back seat fitted as standard
• Reliable, tight shut-off by extended seal faces – also after regrinding the seat/disc interface
• Long service life and high functional reliability thanks to non-rotating stem with burnished shank, hard-faced seat/disc interface made of wear- and corrosion-resistant materials and stellited seat/disc interface as a standard
• Threaded bush free from non-ferrous metals, for versatile application

Gate valves in a nutshell

This is how gate valves work

Gate valves belong to the family of shut-off valves and are generally fitted in piping systems or water pipes. They are suitable for completely open or closed use. Gate valves can isolate parts of the piping system or redirect the flow of the fluid handled, for example for maintenance work at downstream valves and systems. They are mostly used in above-floor and underfloor systems when the pressure loss has to be kept to a minimum.

Actuation is effected by a simple rotational movement of the stem. The gate valve disc moves up and down on the thread of the stem. This allows the pipe to be opened or closed as required.

KSB gate valves are not only absolutely reliable, they are also individually tailored to your needs. Enabled by innovative methods, the latest technology and our experts’ know-how: KSB always satisfies the special requirements of operators, consultants and engineering contractors.

KSB gate valves: robust and versatile in use

Gate valves are versatile and can be used in many applications. They are particularly suitable for fluids such as water, steam, gas, oil and other non-aggressive fluids. Especially in power stations, gate valves play an important role. They are in charge of reliably sealing off water and steam while withstanding enormous pressures and temperatures and meeting demanding standards and codes such as DIN / EN, ASME / ANSI or IBR. Whether they are used for condensate, feed water or steam systems, valves in power stations are governed by the most stringent regulations and directives. These are met by KSB's high-quality products one hundred percent.
