Aren't there cases that require countermeasures to allow high or low-temperature working fluids?

In this article, we will introduce two cases related to customized valve temperature specifications desired across various industries.

Case 1:

• I. Customization Requests
  (1) Change temperature specifications
  (2) Lower power consumption

• II. Background:
  ・Field (Industry): Energy
  ・Country or Region: Asia
  ・Application: To develop fuel cells for power generation in polar regions.
  ・Problem : I am looking for a valve with a low power consumption of 1W or less, and to be used at extremely low temperatures of -30℃.

• III. Base Product Information
  ・Click here for the Diaphragm Valve - EXV series


• IV. Customization :
  ・The coil power and sealing force are optimally designed with a power consumption of 0.7W.
  ・By changing the design from a diaphragm type to a non-diaphragm one, we succeeded in the design of a valve that can be used even in low-temperature environments.

Note: Details such as specifications, etc., may be changed without notice.

Case 2:

• I. Customization Request
  Change temperature specifications

• II. Background:
  ・Field (Industry): Energy
  ・Country or Region: Asia
  ・Application: In response to the factory exhaust gas regulations, a new exhaust gas monitoring device is under development. This valve will be a part of the new device.
  ・Problem :The valve should be compatible with a highly corrosive exhaust gas & must function in a high-temperature environment.

• III. Base Product Information
  ・Click here for the Diaphragm Valve - PKV series

• IV. Customization :
  ・By adopting appropriate material & implementing heat transfer measures, this valve can handle corrosive gases up to 200℃. The heat transfer measures include revised internal construction & addition of Ventiducts.
  ・The heat arising from the actuator has also been suppressed to a great extent due to the inclusion of a Hit & Hold circuit.
