Hydraulic drives

BHS Hydraulic Drive

BHS hydraulic drive has the most compact design. This type of drive is used in places with strict dimensional requirements – on offshore platform, for instance. This drive is used as well on downhole storm chokes, where hydraulic fluid is required.

Hydraulic drives Hydraulic drives

Basic features – easy maintenance owing to the valve stem fast make-up connection and the clamp connection between actuating cylinder and valve cap.

Standard design: according to API 6A

Product line:

  • 1 13/16" to 9" API 5000
  • All classes for 2" to 18" API 6D sliding gates

Auxiliaries:

  • Magnetic operated limit switch
  • Manual override
  • Hydraulic opener
  • Temperature-sensitive open position fixation
  • Quick exhaust valve + manual shutoff and discharge valve

BHA / BHAWC Hydraulic Drive

Hydraulic drives

BHA hydraulic drives are used for matching with different API 6A and API 6D gate valves for ground and offshore units. These drives may be used for various applications with gate valves on pipelines, extracting and processing industries, or other equipment using gate valves. This drive is designed for easy adaptability to BPA pneumatic drive.

BHA-WC series drive is capable of the cable cutting-off during cable operations in case of complications with cables, when the well shutdown procedure is recommended. The drive provides force sufficient for 0,108 wire cutting, 7/32 stranded rope, or flexible tubing, securely closing the well. BHA-type and BHA-WC-type are replaceable on the same gate.

  • Movable device with remote control
  • Inner pressure compensator
  • Stem position spindle

BHDD Hydraulic Drive

Hydraulic drives

BHDD double-acting linear hydraulic drives are designed for matching with various sliding gates according to API 6A and API 6D. BHDD drives may be used for various applications with gate valves on pipelines, shutoff and release valves, and in processing industry, or on other equipment using sliding gates.

Standard design: according to API 6A or customer’s requirements

Product line:

  • API 2000 – 15000 for1 13/16" to 13 5/8" API 6A sliding gates

Auxiliaries:

  • Magnetic operated limit switch
  • Manual override
  • Quick exhaust valve
  • Manual pump for the sliding gate closing or opening

BSC Step Drive

step hydraulic drive

step hydraulic drive

BSC step drive is designed for remote control of the cage-type throttle valves (with holder). Drive piston movement activates disc 36° turning clockwise and counter-clockwise per every cycle providing throttle valve high precision work. Maximum output torque exceeds the potential maximum required by the throttle valve providing maximum service life. BSC drive is designed for compatibility with manual throttle valve.

The drive may be equipped with hydraulic or pneumatic supply source.

Standard design: according to API 6A or customer’s requirements

Product line::

  • API 2000 – 5000 for API 6A2 sliding gates for 2 1/16" to 7 1/16"
  • and for 1 13/16" to 4 1/16" API 10000 - 15000

Auxiliaries:

  • Transducer 4-20mA for the throttle position remote control
  • Limit switches detecting the full throttle or full closing
  • Manual override

Example:

  • Well-control equipment for offshore platform installation
  • Drive type: BHAWC
  • Pressure: 3000-5000 psi
  • Temperature: -46°C... +200°C
  • Medium type: hydraulic oil


Pneumatic drives

BPA Pneumatic Drive

BPA pneumatic drives are perfect for down hole storm chokes and release / blowdown valves. BPA drives are mountable on various sliding gates manufactured in accordance with API 6A and API 6D specifications.

BPA drives are designed and manufactured in compliance with the highest industry standards and provide long life and easy maintenance. BPA drives may be used instead of the BHA hydraulic drives if required.
