Frequently Asked Questions
Q1: What is the difference between DBDS6P1X and DBDS6K1X?
The "P" in the model code indicates Subplate Mounting (ISO 4401 interface), while "K" indicates a Screw-in Cartridge design. The DBDS6P1X is a complete valve assembly with a body and ports, whereas the DBDS6K1X is a cartridge that inserts into a custom manifold block.
Q2: Can I adjust the pressure beyond 200 bar?
No. The "/200" suffix denotes the 200 bar pressure stage spring. Although the valve body can withstand up to 400 bar, the spring is calibrated for a maximum reliable setting of 200 bar. Attempting to exceed this will result in inaccurate pressure control and potential spring damage.
Q3: Is this valve suitable for water glycol (HFC) fluids?
Yes. The standard NBR seals used in this model are compatible with HFC water glycol fluids. However, for phosphate ester (HFD) fluids, a variant with FKM (Viton) seals (typically denoted by a /V suffix) is required.
Q4: Why is my valve leaking or not holding pressure?
Common causes include:
Contamination: Dirt or debris preventing the poppet from sealing. Ensure ISO 4406 20/18/15 cleanliness.
Damaged Seal: Check for worn or extruded NBR seals.
Over-tightening: Excessive torque on the adjustment mechanism can damage internal components.
Q5: What is the effect of backpressure at the T (tank) port?
Backpressure is fully additive. Any pressure at the T-port is added to the spring setting. For example, if the valve is set to 180 bar and the T-port has 20 bar of backpressure, the system will relieve at 200 bar. Ensure the total pressure does not exceed the valve's maximum rating.
