  • Page 17: General Information

    1 General Information The expanding gate valve is a unidirectional non-rising stem manual operated valve incorporating an expanding gate and seats design. The parallel expanding gate design provides a tight mechanical seal which is normally unaffected by pressure fluctuations or variations. The gate assembly uses an wedge face which is collapsed during travel.
  • Page 18: Installation

    2 Installation 2.1 Unpacking a) The valve is shipped in full open position with flange end protectors installed. This is to preclude debris from falling into valve cavity. b) Remove flange protectors and thoroughly inspect interior of valve and end connections for damage or foreign material.

  • Page 20: Operation

    3 Operation Turn the hand-wheel clockwise to CLOSE the valve until it becomes tight. Tighten securely to mechanically energize the seal. DO NOT BACK OFF THE HAND-WHEEL. Turn the hand-wheel counter-clockwise to OPEN the valve until segment is stopped by the bonnet. If necessary, with the valve fully CLOSED, cavity pressure can be relieved through the body vent fitting.

    this position. Inject grease into the valve cavity through the other body grease fitting. Once completion of lubrication, remove releasing tool and grease pump. Re-install grease fitting caps securely on the both fittings. CAUTION: Lubricating pressure must not exceed the rated working pressure of the valve being lubricated.
  • Page 22: Draining

    If necessary, repeat injection of the injectable packing until sufficient to eliminate leakage. WARNING: Always face away from the fittings during packing injection. CAUTION: Over pressurizing the injectable packing will distort packing, making the valve difficult to operate. 4.4 Draining Routine draining will reduce damage to valve caused by accumulation of foreign material in the valve body.
