    1. Valve seat adopts the structure of O-ring seals and pretightening float valve seat, the soft sealing inlays fluoroplastic, it provides the function of double sealing: fluoroplastic to metal and metal to metal. And at the same time, the fluoroplastic can remove the dirt of the gate disk.Product Features

    2. Of the metal to metal sealing, there is a grease injection structure outside the valve, grease injects the sealing part through the seat, in this way achieves the aim of zero leakage.

    3. Through conduit gate valve always coincide with the sealing surface,whether the disc is full open-or fullclosd; sealing surface to be protected from scouring by media dilectly, thereby extending the service life. In fulltime, smooth channel for the direct and flow resistance coefficient is extremely small, no pressure loss, leading to Pig.


    BODY & BONNET
    The design of the body and bonnet is calculated to achieve the most regular distribution of stress in all directions, as well as the minimum turbulence and resistance to flow. Valve bonnets are equipped with a backseat bushing. The yoke is integrally cast on Pressure Classes 150 and 300 up to 12” and up to 10” on Class 600 and higher ratings.

    GATE
    All gates are fully guided to the seats. As standard our valves are supplied with a solid flexible gate that has a tapered H cross-section. The flexible wedge is cast or machined with a circumferential groove to allow the seating surfaces to move independently and adjust to movement of the body seats. This design is beneficial where line loads or thermal expansion of the system is likely to distort the seat face in the valve. This design of gate is ideally suited for steam or other high temperature services and is especially useful to prevent sticking where valves are closed when hot and opened when cold.

    SEAT RING
    Seat rings are designed to greatly reduce and/or prevent any turbulence and avoid damages due to the corrosion. The seat rings are forged or rolled in one piece, and then seal welded and overlaid, if required. After welding and all required heat treating, the seat ring faces are machined, thoroughly cleaned and inspected before leaving for assembly.

    STEM
    The stem connection to the gate is a T-head design which is integral (without welding) with the stem. The accuracy in the dimensions and finishes assure a long life with a perfect tightness in the packing area, resulting in lower fugitive emissions. The stem-to-gate connection is designed to
    prevent the turning or the disengagement of stem from the wedge while the valve is in service. Through calculations and extreme testing, the strength of the stem-to-gate connection has proven to exceed the strength of the stem at the root of its operating thread.

    STEM PACKING
    The stem packing is designed and arranged to ensure a maximum seal along the stem during operation or while at position,
    thus allowing for a greater reduction in fugitive emissions. Our packings are NONASBESTOS types.
    Kelite Valve can supply any style of packing required by our customer.

    STUFFING BOX
    The depth of the stuffing box allows for a sufficient amount of packing, which makes the stem seal. Our standard packing arrangement and stuffing box design meets <100 ppm fugitive emission requirements. If specified in the purchase order, lantern rings and/or grease injectors can be furnished.

    PACKING GLAND
    The packing gland design is a two-piece self-aligning type. The packing gland has a spherical head that rides within the spherical joint of the gland flange. The packing gland has a shoulder, which restricts the complete entry into the stuffing box bore. This particular design assures a straight compression of the packing as the gland eyebolts are being equally adjusted, without injuring the stem.

    STEM NUT
    The stem nut arrangement and design allows for the removal of the handwheel without allowing the stem and gate to drop into the closed position if the handwheel is removed while the valve is in the open position. Ball bearings are provided in the stem nut arrangement of Class 150 valves from NPS 14”, on Class 300 valves from NPS 12:, on Class 600 valves from NPS 6”, and on Classes 900-1500 valves from NPS 2”.

    HANDWHEELS
    Handwheels are designed for easy operation and a comfortable grip. Our valves are also available with gearing, motor actuators or cylinder actuators for the more demanding services.

    BOLTS AND NUTS
    For normal service conditions, ASTM A194 Class 2H and ASTM A193 Grade B7 nuts and stud bolts are furnished. If specified for high temperature service conditions, ASTM A194 Class 4 and ASTM A193 Grade B16 nuts and stud bolts are furnished. Standard bolting furnished for our stainless steel valves consists of ASTM A194 Class 8 and ASTM A193 Grade B8 nuts and stud bolts.
    Kelite Valve can supply any bolting as required by the customer.
