Gate valve

SCOTON gate valve with single gate and full bore. Suitable for double flange, thread end and special connection. Pressure range: 2000psi to 20000 psi. DN size: 1 13/16" to 9",  Can used with our SCOTON actuator.

Main features of  Wellhead Gate Valves are as follow

  • Double-way downstream Sealing structure, prolong service life.
  • Fixed metal seal, (between gate and seat, seat and body)
  • Simple, reliable gate and seat design can reduce site service and keep the minimum spare parts storage.
  • The sealing ring between seat and body can help to seal in low pressure environment, it also can prevent granular pollutant goes into valve bore and sealing area.
  • Stem seal design covers all pressure range and temperature range, and all fluid environment in well head and manifold.
  • Metal seal between bonnet and body.
  • Stem back seal structure allows valve replace stem seal under pressure activate.
  • To ensure safety, injection device can put behind of stem back seal, it can put on bonnet and eliminate body leak.
  • Low open-close torque, easily to open and close.
  • Working Pressure: 2000PSI～20000PSI
  • Nominal Bore: 1 13/16"～9" (46mm～230mm)
  • Working Medium: oil、natural gas、mud and gas containing H2S、CO2
  • Working Temperature: -46°C～121°C（Class LU）
  • Material Class: AA、BB、CC、DD、EE、FF、HH
  • Specification level: PSL1-4
  • Performance Requirement: PR1-2

Koomey Unit (BOP Control System)

图片
Koomey unit ( BOP control system ) for surface BOP stacks is very important equipment which controls BOP stacks and gate valves controlled by hydraulic pressure especially in drilling and workover operations. It is necessary to accurately operate and maintain the hydraulic control system. The hydraulic control system manufactured by SCOTON can be divided into 3 types: Directly manually operated FK series hydraulic control system The hydraulic control system not fitted with a driller's console is applicable to drilling or workover operations and is simple and portable. The hydraulic control system can be fitted with a mechanical anti-lifting device (see the operation manual for the anti-lifting device). Pneumatic liquid type FKQ hydraulic control system This hydraulic control system is fitted with a driller's console or an auxiliary driller's console (optional). Alarm type and non-alarm type driller's console and auxiliary driller's console can be installe

Wireline BOP

图片
The wireline BOP is used for sealing the wellhead to prevent well blowout accidents is logging operation when there are accidents and there are cables in the well. The  wireline BOP has simple structure, convenient application and maintenance, small volume, light weight, high pressure bearing, hydraulic remote control and simple and reliable operation. The BOP is mainly composed of main casing, and ram assembly piston, hydraulic cylinder, lead screw, end cap, hand wheel and other spare parts, which are moving in the main casing in opposite direction. When the well needs to be sealed, the hydraulic control and grease injection pressure control system is pressurized to push the piston, thereby leading the two ram bodies to move towards the center of the well bore, and well sealing can be achieved through the associative action of the front rubber sealing element and the top sealing rubber. The ram can be locked on the shut-in position through clockwise rotating the locking hand wheel. W
