XDV Cast Steel Gate valves are designed and manufactured to ensure leakage of less than 100 pm (parts per million) of volatile organic compounds. Extensive base line laboratory testing (static and cycle testing) has been performed establishing critical design parameters necessary to achieve low emission sealing in the XDV stem packing seal area and in the bonnet gasket sealing area, n-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the XDV Cast Steel Gate XDV meeting a maximum of 100 ppm voC leakage prior to shipment

XDV Universal Cast Steel Check Valves are designed and manufactured stricty to International Standards APl6D, BS1868, ASMEB16.34 or Equivalent, or reduce the flow resistance and pressure drop to the minimum possible extend, which is suitable to be mounted in horizontal postion only, lapped and screwed in seat ring ensures tight shut of and long duration service. valves disc is perfectly designed, accurately machined and guided for efficient automatic shut off at zero pressure, with a feature of compact structure & Low emission service. In both Swing & Piston Constructions.

Axial Flow check valves from XDV are designed and manufactured stictly to updated International Standards of APl 6D, ASME B16.34 or Equivalent. axial check valve is the preferred solution for critical non-return applications such as the protection of rotating equipment and systems where low pressure loss, stable operation and dynamic behaviour are essential.

XDV Cast Steel Globe Valves are designed and manufactured to ensure leakage of less than 100 ppm (parts per million) of volatile organic compounds. Extensive base line laboratory testing (static and cycle testing) has been performed establishing critical design parameters necessary to achieve low emission sealing in the XDV stem packing seal area and in the bonnet gasket sealing area, ln-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the XDV Cast Steel Globe Valves meeting a maximum of 100 ppm voC leakage prior to shipment

The XDV knife gate valve is designed for general industrial service applications. The design of the body and seat assures non-clogging shutoff on suspended solids in industries such as: Pulp and Paper & Power plants & wastewater treatment plants & Chemical plants & Food and Beverage & Buk handling Mining knife gate valve manufactured by XDV is Bi-directional Designed (optional) sealing in both flow directions, with integrated scraper system and free flow passage. XDV Knife Gate valve is built with a cast body and features a heavy-duty stainless steel blade. Removable seats on either side of the gate provide a bi-directional bubble tight seal, with no metal parts in contact with the slurry.

XDV Slab Through Conduit Gate Valves are manufactured with a full bore port, rising stem OS&Y and with floating seats and gate, pressure energized, for a bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.
