Whether RV1, RV2, RV3 or RV4, the proportional relief valves of each series of Hikelok have always been reassuring in ensuring safety and rapid response.
RV1
The valve is sealed in the form of sealing ring, and Hikelok adopts high-quality sealing ring, which can provide better sealing effect and eliminate the risk of external leakage of the valve; In addition, by optimizing the valve stem structure, the influence of back pressure on the valve is minimized to ensure the accurate opening pressure of the valve; The applicable range of the spring can be easily replaced through the spring.
RV2
The valve adopts the sealing form of adhesive disc structure, and the sealing ring is bonded to the support disc with a specific process. This structure increases the contact area with the medium and ensures the stability of the sealing structure on the one hand; On the other hand, it can make the valve open under low pressure with sensitive action and more accurate opening pressure; The O-ring seal is used between the valve body and bonnet to eliminate the potential risk of external leakage of the valve.
RV3
The adhesive disc used for sealing of the valve is an integrated design with the valve stem. This structure has the characteristics of stability and high strength, which increases the service life of the valve stem; The O-ring seal is used between the valve body and bonnet to eliminate the potential risk of external leakage of the valve; Compared with other RV series, RV3 has the characteristics of large diameter and large flow.
RV4
RV4 series eliminates the sealing ring at the valve stem position, reduces the friction resistance caused by the seal, and the valve can be opened and closed accurately under very low pressure; Because there is no sealing effect at the valve stem, the medium will penetrate into the working area of the spring, so a sealing ring is added between the valve cap and the spring gland to prevent medium leakage.

The RV series proportional relief valve of Hikelok can calibrate the opening pressure value before delivery according to the customer's requirements. The valve has different color labels representing different pressure setting ranges. It can be equipped with anti loose wire, lead seal and nameplate when leaving the factory. When the pressure range is consistent, each series can be equipped with an override handle. The handle can control the valve to release pressure in advance. When the valve does not release pressure under the opening pressure, emergency measures can be taken to release pressure by lifting the handle to ensure operation safety.
