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. “
Metal seated butterfly valve
Type VSS / VSSL (Somas)
Pressure: 25
Nominal size: 80-1200
“The Somas metal seated butterfly / shut-off and control valve type VSS is suitable for controlling and shutting off liquids, steam and gases over a wide temperature range.
The triple eccentric design allows the use of a solid stainless steel seat due to the special contour of the disc. The disc geometry and the shape of the seat provide excellent tightness.
The seat is resistant to high flow velocities and ensures good tightness, even under difficult operating conditions. The seat, which is available in different materials, can be replaced.
The VSS valve was developed as a wafer valve and can also be supplied as a lug type valve (with threaded bores).”
Double eccentric butterfly valve
Type EAK (ERHARD)
Pressure: '6 / 10 / 16 / 25 / 40
Nominal size: 700 - 3600
The double eccentric butterfly valve EAK is used in water applications with large nominal diameters.
The butterfly valve offers a modular actuator concept through the use of a handwheel, electric actuator, stem extension, weight-loaded hydraulic actuator, pneumatic actuator or chainwheel.
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”
