  • The Valbart VW1 is a API 6D-compliant, welded-body valve that seals off both seats at the same time and allows bleeding of the entrapped cavity pressure (double block and bleed) with the ball in the closed position.
    Welded-Body Side-Entry
  • The Valbart Cryogenic Ball Valve meets demanding end-user requirements for leak rate and fugitive emission performance. It's body construction and flexible trim configurations ensure proper safe isolation. It is bi-directional (std) or uni-directional (upon request), side entry or top entry with fire-safe design, with an anti-static feature and automatic cavity relief.
    Cryogenic Side-Entry
  • Double Block and Bleed Valve is a side-entry ball valve, with either a bolted or welded body, designed for use in upstream, midstream and downstream oil and gas applications. It requires two in-line isolation valves and a bleed valve used to drain or vent trapped fluid between the two closure elements in order to safely isolate the downstream pipe. This feature can be achieved with one single valves complete with a bleed port between the obturators.
    Double Ball & Operator Side-Entry
  • The NAF Trunnball DL is a full-bore trunnion-mounted ball valve, developed by Flowserve engineers with more than 80 years of experience manufacturing ball valves. The ball is supported by two large, low friction trunnion bearings for consistent low torque even at high differential pressures. Due to its bi-directional tightness, low friction and high controllability, it is an excellent choice for isolation, on/off and modulating control applications.

    End-Entry Small Bored
  • The Argus FK75C split-body, full-bore, floating ball valve represents the highest standards in valve technology. Its superfine-finished, seat-supported ball is just one of its many important design features. Others include an anti-blow out stem, long-life, double-stem seal system and stem supported in bearings to ensure seals are free from operation loads.
    Split-Body Chemical Coated & Cladded
  • The Duball DL is a high-performance, metal-seated, full-bore ball valve, equally suitable for isolation, on-off and modulating control applications. The excellent characteristics of NAF Duball DL are particularly beneficial under the most challenging operating conditions in the process industry, where difficult media and demanding pressure conditions make severe demands on the design, materials and performance.
  • Valbart top entry ball valves are in-line repairable and ensure bi-directional sealing with two independent floating seats. They feature a double block and bleed, fire safe design and an anti blow-out stem.
    API 6D/6A Top-Entry
  • The Valbart Rising Stem Ball Valve (RSBV) is the oil and gas industry's choice for applications requiring a mechanically energized metal seat or soft-seat to safeguard against losses from process contamination or leakage of material. Whether your needs call for molecular sieve switching, isomerization, thermal oil, high/low temperatures or critical services, the RSBV provides an unmatched level of robustness, reliability, and convenience.
    Rising Stem Ball Valve
  • Valbart designed the Trunnion Mounted Control Ball Valve (TMCBV) to operate at high pressures while minimizing the torque needed to operate the valve. The spring-loaded, process energized seats offer tight (Class IV and Class V) shutoff at any pressure. In most cases, the TMCBV's capacity is greater than that of a comparable globe valve. This allows the customer to use a smaller, lighter valve and experience cascading savings. This valve also requires a smaller, less expensive actuator and less expensive pipe supports.
    Trunnion Mounted Ball Control
  • The NAF Duball DL Pocket Valve is the pulp and paper industry's choice for a reliable and robust valve solution that allows for safe removal of sand or debris in separator and junk trap applications during normal process operation. Building on years of experience in providing flow control solutions in harsh environments, the Duball DL Pocket Valve is specifically designed to ensure continuous process uptime and throughput by allowing process pressure to be maintained while unwanted process particles are eliminated.
  • The NAF Duball DL Ceramic is a ball valve that is internally lined with ceramic for erosive and abrasive media. It is primarily intended for control but has a sealing class as for a shut-off valve. The valve represents a concrete result of our product philosophy which is focused on functionality, high quality and low life cycle costs, and is based on concentrating our range to a limited number of valve types, but all of them suitable for a wide variety of applications.
    Ceramic Lined and Ball
  • NAF Setball ProCap Segmented Ball Valves are unique high-tech capping valves designed for automated filling of wood chips for batch digester applications in the pulp industry.
    Capping Valve
  • The Valbart TCSGV through conduit slab gate valve is the oil and gas industry's choice for liquid and gas applications requiring reliable, tight shut-off to prevent leakage and minimize losses from process contamination. It is ideal for pipeline applications requiring pigging capability. Its full-bore design features spring-energized seats and a floating slab gate to ensure both low- and high-pressure sealing capabilities. The Valbart TCSGV is manufactured and tested in accordance with API 6D, latest edition. Its design is fully compliant to ASME Section VIII, Division 1. Its design meets API 6D isolation features of block and bleed, double isolation bleed (DIB), double block and bleed, cavity relief, and other requirements commonly specified in the pipeline industry.
    Through Conduit Slab
  • The Valbart CEGV compact expanding gate valve is a fabricated body-expanding gate valve manufactured andtested in accordance with API 6D, latest edition. The compact expanding gate design features a full-bore diameter, with a compact, non-through conduit design providing a compact and lightweight valve package. Valbart expanding gate valves are engineered to achieve tight shutoff at high and/or low pressures in liquid or gas services. The expanding gate and segment design provides a high-integrity seal for a variety of critical applications, while affording lower operating friction.
    Compact Expanding Gate
  • The axial design allows for a streamlined flow path around the disc and high pressure recovery, minimising pressure drop across the valve. The efficient design combined with the highly responsive non-slam operation make this valve ideal for high head, critical pump applications. Its optimum designed aerodynamic flow path through the valve results in very low pressure losses. It is also available with the API 6D face-to-face dimensions (Series ZD)
    Solid Disc Centre Guided
  • Noreva's NC is a lower cost solution which combines the advantages of the NZ with a shorter face-to-face length and reduced weight, where marginally higher pressure drops are acceptable. The NC is specially designed for gas applications having a centrally guided, single spring with very low fully open velocity. The design is focused on laying the centre of gravity of the only moving part, the disc, over the centre of the surface it is sliding on. Due to this design change, the NC is able to use softer springs, which function at very low flow rates, mainly because the tilting effect of the moving component is eliminated all together.
