Ball valves and Flow Control Valves
Our basic program
More than 30,000 ball valves, flow control valves, check valves and accessories always in stock.
Our ball valves are available in sizes ranging from DN4 (1/8”) to DN200 (8”) and, depending on the design, can withstand pressure of up to 2,000 bar. With more than 15 connection types, we meet all international requirements (e.g. ISO228 - BSPP, ANSI B1.20.1 NPT, ISO6162-1/2, ISO 6164, ISO 8434-1, …).
Our ball valves and needle valves are available in steel or stainless steel (AISI 316Ti/L) as standard. However, we also offer such special materials as Duplex, Superduplex and Hastelloy.
Accessories & Options
Our standard ball valves are available in numerous designs and can be expanded with accessories such as locking devices, limit switches, additional assembly bores, actuators, and much more.
Our tamper-proof locking devices guarantee safety against unintendant actuation of ball valves.
A detent mechanism prevents the unintentional actuation of a ball valve.
For the direct assembly of ball valves.
Pneumatic, electric and hydraulic actuators for ball valves.
More than 15 connector types. Mixed connector types on valve inlet and outlet possible.
We offer mechanical and proximity limit switches with assembling sets.
Combination of two or more valves in one block. With bleed- and bypass functions.
The marking of each ball valve housing with its internal traceability number allows complete traceability right back to the smelting of the raw material.
High corrosion protection
On request, we can supply ball valves with resistance to red rust up to three times better than simple zinc coatings.
