• Pressure Relief Function: The cap is engineered to minimize the pressure behind it in the event that upstream closures fail, providing a safeguard for the operator.

• Pressure Detection: It is designed to alert the operator if there is any pressure behind the cap, signaling the possibility of an upstream valve failure.

• Primary Closure Certification: When used in combination with Todo-Matic or Todo-Gas couplings, the cap system is certified as a primary closure, ensuring it meets rigorous safety standards.

• Custom Sealing Options: The cap can be custom-sealed to prevent unauthorized tampering or operation, enhancing security and safety.

• High-Level Passive Safety: The design of the coupling and cap system incorporates a number of safety features, making it unique in the market for its passive safety mechanisms.

• Working Temperature Range: -20°C to +80°C (-4°F to +176°F)
• Working Pressure: 25 bar (363 psi)
• Stainless Steel: 316L, known for its corrosion resistance and excellent performance in a wide range of chemical and industrial applications.
