16.0MPa Slide Gate Valve

High Pressure API 6D Self Relieving Spring Loaded Parallel Slide Gate Valve For Gas Oil


The Parallel Slide Gate Valves are mainly used in the field chemical, petroleum, natural gas designed to provide isolation and transmission of flow in a piping system or a component when closed, sometimes can be installed in the pump outlet for regulating or control of flow. It’s characterized by compact structure, reliable closing and good sealing performance, which can be furnished for high differential pressure services or where thermal. The parallel gate valve can be driven by the handwheel, electric motor, pneumatic and hydraulic

Parallel slide gate valve applications

  1. Oil and natural gas production wellhead device, conveying and storage pipelines (Class150~900/PN1.0~16.0MPa, operating temperature -29~121℃).
  2. Pipes with suspended particle media.
  3. Urban gas pipeline.
  4. Water engineering.


Main Features


  • Two discs and just one wedge design gate valve.
  • Parallel slide gate valve provides a smooth flow path between seats.
  • This design of gate valve is commonly used for clean fluids and steam applications.
  • System pressure is used to provide isolation. The closing is only made over one of the seats. The higher pressure in the system, the better closing tightness.
  • The discs have a certain movement to assure its right alignment with the seats contact faces when closing (seal is established on outlet seat face only), avoiding any mechanical stress.
  • The inconel spring located between both discs, provides initial seating force. Once the discs are in the right position, no additional torque is necessary to achieve a positive seal.
  • Torque requirement is lower than other gate valves as wedge type because needs lower operative forces.
  • The wiping action of the discs over seats while the valve is operating removes debris and prevents premature wear of the components. A long life service is guaranteed by means of hardening seats and discs with an extra hard material as Stellite 6, Tribaloy or others.
  • Parallel slide system avoids jamming related to cooling down of the pipeline.
  • A wide range of construction materials, actuation systems and accessories are available for each case.
