Centric flanged / double flanged butterfly valve
(TTV)
Soft seated, butterfly valve
Type GRW (Zwischenflansch) / GRL (Anflansch) (Emerson)
Pressure: 16bar (DN20-DN300) 10bar(DN350-DN900)
Nominal size: DN20-DN900
“The Emreson resilient seated butterfly valve is a centric butterfly valve with a split shaft (up to DN300), rounded polished disc edge, centring bores on the valve housing and an extended valve neck allows for pipe insulation.
The type GRW is designed as a wafer type valve and the GRL as a flanged type valve according to EN558 series 20, with a spheroidal cast iron housing and a disc in 1.4408 steel. “
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”
Plastic butterfly valve
Type EXTREME series (CEPEX)
Pressure: '6 / 10
Nominal size: 50 - 300
The CEPEX plastic butterfly valves can be used to shut off and control liquids.
The valves made entirely of plastic have the advantage that they are resistant to chemicals. The EXTREME series is designed for special requirements and can therefore be used in steel plants, chemical plants or the oil industry.
The plastic butterfly valve can be operated either manually or also automatically and is available in a wide variety of plastics (PVC-U, CPVC, PP-H, PVDF and ABS).
