Dry Contact controlled Retrofit-Motor for Gate Valves

SKU: KFRDRY01
Version: 1.1 (May 25)

1. Product Description

The motor drive designed for angle seat valves, specifically KFR valves, offers a solution for seamlessly retrofitting existing shut-off valves into remotely controlled intelligent devices. This process is achieved without the need to interrupt water supply or cut into the water pipe. The 12V-powered motor is not only water-resistant but also resistant to dirt, ensuring durability up to the power supply. Versatility is achieved through various adapter rings and a sophisticated connection system, allowing the motor to be compatible with modern angle seat valves featuring raising or non-raising stems, ranging from DN15 to DN32.

Incorporating an additional water sensor directly connected to the device enhances functionality, enabling the motor to serve as a leak protection system without the need for further configuration or wireless connectivity. The servo motor's waterproof design makes it suitable for deployment in damp, dirty, and outdoor environments. In its open state, the motor autonomously conducts valve training weekly, involving a closing/opening action by 1/8 turn to remove dirt and scale.

The device is controlled either through the local button or via a dry wire switch input of the existing smart home system (Shelly, Z-Wave, Smartthings, Bosch, Homematic, ...) or your alarm system.

3.1. Mounting the motor on the valve

The motor drive can be used with all commercially available angle seat valves. However, due to the variety of mechanisms, certain adjustments must be made. When installing, the valve should be normally open (installers recommend opening the valve fully and then closing it slightly with approx. 2 clockwise turns).

  1. First, loosen the screw in the center of the handwheel using a screwdriver. Some manufacturers do not use the typical green handwheel. The spindle may be hidden under plastic, but will always have a screw on top and a square end. Keep the screw for later use.
  2. Now remove the handwheel.
  3. Select one of the 4 adapters (A1...A4) for wrench sizes M17, M22, M27, or M30 that fits well onto the bottom of the valve top (hexagonal or rectangular shape). If none of the supplied adapters fits the valve, refer to the “Custom Adapter” section for further guidance.
  4. Select the correct ball bearing seat (W1 ... W3) and place it on the spindle. If the spindle is larger than 8x8 mm, which is required for the largest ball bearing seat, this product cannot be used for this valve. If the spindle is smaller than the smallest ball bearing seat of 6x6 mm, the issue can be resolved similarly to the adapter case. See the instructions in the “Custom Adapter” section.
  5. Now fix the ball bearing seat with the screw from step 1.
  6. Depending on the size of the valve top and spindle, additional spacer rings (D1, D2) may be required on the adapter ring. If the inner coupler (K) cannot be pushed all the way into the main housing (G) without resting on the valve housing, or if the main housing does not reach the already installed adapter ring, a spacer ring (D1 or D2) must be placed between the adapter ring (Ax) and the main housing (G). This is usually the case with rising spindle valves. The spacer rings are 12 or 24 mm in size and can also be combined into a 26 mm ring. The spare handwheel can be used to test the opening and closing of the valve.
  7. Now place the housing (G) onto the adapter or spacer ring.
  8. Insert the inner coupler into the housing. It must reach over the ball bearings in both the open and closed positions. The housing is transparent for this purpose.
  9. The retainer (N) is needed to hold the entire assembly in position if the valve is not installed upright. It is recommended to always use the bracket. The complete device is attached to the pipe using the two included cable ties. The cable ties can be removed at any time. To slide the retainer over the housing, the two tabs on the housing must be slightly pressed together. There are two small notches on the inner ring of the retainer for this purpose.
  10. Finally, place the motor head onto the housing. Sometimes the inner coupler must be slightly rotated so that the gear structure of the motor meshes with the inner coupler.

3.2. Valves from Wilhelm Ewe GmbH and Co. KG

The valves from this company have a unique design. You must insert the split ring (E1+E2) into the 24 mm spacer ring (D1) instead of using one of the adapters A1 ... A4. A small additional spacer ring (DE) is placed directly under the ball bearing seat to fix the valve's grease chamber.

3.3. Custom Adapter

If no suitable adapter is available for the valve seat, a custom one must be made. To do this, select an adapter that fits over the valve seat and fill the gap with a two-component resin. This resin is included with the motor. Cut off a piece of the compound with a utility knife and knead it until a uniform color is achieved. Then fill the gaps between the adapter ring and the valve base. After the resin has hardened, the now custom-fit adapter ring can be used.

Note: The resin will adhere firmly to the valve. If this is not desired, lightly oil the valve beforehand. Then the hardened adapter ring can be removed more easily.

Similarly, a ball bearing seat can be adapted for a valve shaft with a square smaller than 6x6 mm. Ensure that the spindle is precisely centered in the ball bearing seat.

3.4. Setting the End Positions of the Motor Drive

Once the motor is mounted and powered, it must determine the correct end positions for the ‘OPEN’ and ‘CLOSE’ positions:

  1. Manually turn the valve to the ‘OPEN’ position before the motor is initially installed. According to installer recommendations, the optimal ‘OPEN’ position is about 2 turns towards ‘CLOSE’ after reaching the stop in the ‘OPEN’ direction (counterclockwise).
  2. Power the motor.
  3. Press the button briefly once. The motor will now move briefly in both directions and determine whether it is in the ‘OPEN’ or, contrary to the recommendation in step 1, in the ‘CLOSE’ position. This information is indicated by the color of the LED on the device.
  4. If the motor was initially in the ‘OPEN’ position, the first ‘CLOSE’ command (either via short button press or external control) will move it fully to the ‘CLOSE’ position and then slightly reverse. This function is intended to relieve the valve's rubber seal. If the seal has become brittle from long-term closing or aging, this may lead to valve leakage in the ‘CLOSE’ position. Therefore, this slight reverse function can be disabled.

Once the end positions are recognized, the motor will no longer forcefully drive against the valve's endpoints, but will instead count the required motor turns and approach the endpoints gently.

8. Disposal Guidelines

Do not dispose of electrical appliances as unsorted municipal waste, use separate collection facilities. Contact your local government for information regarding the collection systems available. If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into the groundwater and get into the food chain, damaging health and well-being.
