china directional hydraulic valves rexroth

Product Information

• - Porting pattern to DIN 24 340 form A,
   - ISO 4401 and CETOP-RP 121 H
  - Wet pin DC or AC solenoids with removable coil
  - Solenoid coil can be rotated through 90¡ã
  - It is not necessary to drain oil when the coil is replaced
  - Fault override button, optional
  - Waterproof pin plug, optional 
  - Large-scope suitable voltage, optional

  Type WE valves are solenoid operated directional spool valves. They control the start, stop and direction of 
  flow.
  The directional control valves consist of housing (1), one or two solenoids (2), the control spool (3), and one or 
  two return springs (4).
  In the de-energised condition the control spool (3) is held in the neutral or initial position by means of return 
  springs (4) (except for impulse spools). The control spool (3) is actuated via wet pin solenoids (2).
  To guarantee satisfactory operation care should be taken to ensure that the solenoid pressure chamber is filled 
  with oil.
  The control spool(3) is moved to the expected position by solenoid(2) and pushing rod(5). This gives free-flow 
  from P to A and B to T or P to B and A to T.
  When solenoid (2) is de-energised, the control spool (3) is returned to its initial position by means of the return 
  springs (4). 
  The solenoids may also control the control spool (3) by an optional override button(6)  under the de-energised 
  condition.
  Type 4WE 6.. L6X/O...(only possible for symbols A, C and D)
  This version has 2 switched positions and 2 solenoids without detent.  
  Type 4WE 6.. L6X/OF... (impulse spool, only for symbols A, C and D)
  This version has 2 switched positions, 2 solenoids and a detent. Both switched positions are thus fixed 
  alternately and so it is unnecessary to continually energise the solenoid.
  Cartridge throttle (type 4WE 6..L6X/¡-/B.. )
  The cartridge throttle is necessary since actual flow may be larger than the 
  performance limits of the valve during switching process.
  This is inserted in the P channel of the directional control valve.
  For application in voltage pulsation, solenoids with large scope voltage
  are recommended.
  For application in high protective grade, waterproof plug should be used.

Tarp Tent

This category is a range of tarp tents, our products are of high quality, easy to carry, available in a variety of sizes,
and adjustable in structure to provide you with a great experience.

The main purpose of a tarp tent is to protect you from the sun and is mostly used in summer when camping and raining.
For example, if you are playing on the beach on a hot summer day, a tarp tent can help protect you from the
strong sunlight, and can also be set up on top of a Camping Tent in the event of rain or snow. There are many
different types of tents, such as canopies and car-side tents (set up with a car as a carrier).

We provide product pictures and basic parameters of each tarp tent and high-qualitytarp tents;
look forward to your cooperation!
