- PPD41L-3 Type Pressure Relief Valve is for low-pressure applications.
- The valve body is equipped with a sealing rubber, so the sealing performance when closing is excellent.
- The valve body material is stainless steel, so no special attention is required for rust prevention.
- If the capacity is insufficient, please use the PLG61-2 type pressure relief valve.
