(TTV)
On/off and control butterfly valves
Type HRD / HRA (Herberholz)
Pressure: max. 2bar
Nominal size: DN15 - DN1200
The throttle valves HRD and HRA are designed as a wafer type valve with a centric valve disc.
Depending on the choice of material, they are designed for operating temperatures up to 1050°C. In the high-temperature version, they have a welded wafer type housing or a one-piece housing.
The throttle valves are suitable for valves according to DIN EN 1092-1 or ASME B16.5 / ASME B16.47, with lengths according to DIN EN 558-1-R20, as well as from DN400 according to the company standard.
The connecting flange is for actuators according to DIN EN ISO 5211.
Testing according to DIN EN 12266.
SIL approval according to ICE 61508 and ICE 61511
Versions:
HRD without seat (leakage approx. 1% of surface equivalent),
HRA metal seated (leakage approx. 0.5% of surface equivalent), HRA with seal ring (leakage approx. 0.3% of surface equivalent),
HRA with metal travel stop ring with seal ring (leakage approx. 0.1% of surface equivalent)
4-offset-eccentric metal seated high performance Quadax butterfly valve
(Quadax)
Pressure: 10 / 16 / 25 / 40 / 63 / 100 / 160
Nominal size: 50 - 1800
“Thanks to its four offset eccentric design and state-of-the-art manufacturing technology, the Quadax valve meets the highest tightness requirements in 100% of cases.
Due to the innovative design principle, even extreme temperatures ranging from –270°C to 800°C are not a problem.
The output cone used on the butterfly is elliptical. The section under a particular angle results in a circular and therefore larger sealing area. As a result, the four offset eccentric high-performance valve is friction-free, has higher Kv values and with absolute tightness.
Available in double flange, lug type, butt weld, gate valve replacement and top entry”
