来源:     发布时间:2016-10-20    点击数:218

Used as a high-pressure safety device, the emergency shutdown valve is normally installed between needle-type pressure regulating valve of wellhead charismas tree and downstream flow meter to ensure the safe production of wellhead and external transportation pipeline. The equipment has adopts the design of full intelligent control system and integral explosion proof, which can meet the requirements of whole life cycle single well production in its early、middle and late period.

Main Parameters and Characteristics

1)Nominal Pressure: 25MPa、35MPa

2)Nominal Diameter: DN50、DN65DN80DN100

3)Working Temperature: -40℃~80

4)With intelligent control system, independently collecting、processingtransmitting and monitoring the production data from the field, meet the need of remote and local setting parameter at the same time

5)With the function of POST、regular self-inspectionremote control self-inspection and manual self-inspection on site

6)Dual super and under voltage control unit(electrical and mechanical control ), mutual independence and non interference

7) With the function of fire alarm and shutdown in emergency in well site

8)With the function of valve-position status display and feedback

9)Perfect performance in weak current, open and shut of low torque mechanical-transmitting  mechanism
