Shut-Off Valves - Globe Valve
While a gate valve is primarily designed for the ‘fully open’ or ‘fully closed’ function, a globe valve (also known as a poppet valve) is ideal for precise flow control. The design with an axially moving disc allows for sensitive throttling of the medium.
A bellows valve is always the first choice when leaks at the spindle must be absolutely ruled out. This is the case with media that are hazardous to health, harmful to the environment, valuable or highly pure. The bellows protects the spindle from the medium and the environment from the medium.
Yes, absolutely. Specially designed shut-off valves for steam are designed for high temperatures and pressures. Look for materials such as 1.0619 steel and sealing components that are approved for steam applications. We will be happy to advise you on this.
TA Luft (Technical Instructions on Air Quality Control) is a German regulation that sets strict limits for emissions from industrial plants. A valve that is ‘TA Luft-compliant’ has a gland packing (usually made of graphite) that complies with these strict emission limits.
