    Metal seated butterfly valve PN40

    Type Typ VSS (Somas)
    Pressure: 40
    Nominal size: 80-600

    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.

    Metal seated DIN swing check valves

    Type 270-570 / 280-580 / 280-580 / 290-590 / 290-590 / 291-591 / 296-596 / 297-597 (R.T. Valvole)
    Pressure: 25 / 40 / 63 / 100 / 160 / 250 / 320
    Nominal size: 50 - 900

    “RT gate valves valvole in cast design are used to prevent backflow in pipe systems. Due to their fully open design, this results in minimal pressure drop.

    Design:
    * The housing material is made of cast steel. The valves have a bolted or pressure seal bonnet (for higher pressure).
    * The valve disc is made with forged material. On request, the disc can be supplied with an overlay of Stellite or other materials.
    * The disc hinge joint is designed in such a way to achieve a
    perfect tightness, which means a self-positioning disc system. “

    Metal seated, DIN flanged ball valve, long pattern, floating

    Type 3563 / 3599 (JC Valves)
    Pressure: 100bar
    Nominal size: 15 - 200

    “The JC Valves metal seated ball valve type 3563 / 3599 is a floating flanged ball valve with a metal seat and long DIN face to face length.

    The standard version of the ball valve includes a anti-blow out stem, an antistatic device, a pressure balancing cavity hole and a “”live loaded”” packing.

    With a wide range of approvals (Fire Safe, Fugitive Emission, ATEX, TRCU, CRN, SIL 3, and many others), it can be used in virtually all industries. A large selection of materials makes the flanged ball valve flexible to use. “

    Type UDV (JC Valves)
    Pressure: 240bar
    Nominal size: 1/2" - 2"

    “The JC Valves type UDV is a metal seated monoblock ball valve that can be used for high pressures up to 240 bar.
    The valve is uni-directional and can be designed with both bolted and welded ends.
    The standard version of the ball valve includes a anti-blow out stem, an antistatic device, a pressure balancing cavity hole and a “”live loaded”” packing.
    Thanks to a wide range of approvals (Fire Safe, Fugitive Emission, ATEX, TRCU, CRN, SIL 3), this monoblock ball valve can be used in virtually all industries. A large selection of materials opens up a wide range of applications. “

    Non contact rising stem ball valve

    Type RSBV (Control Seal)
    Pressure: ANSI 150 - ANSI 2500 (~PN20 - 420)
    Nominal size: 1" - 36"

    Extra robust! Non contact rising stem ball valves are designed for extreme applications. They have a special rotary-axial movement that eliminates any wear and ensures 100% tightness.

    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)
