DELCO ZZYVP-16 Self-operated Nitrogen Seal Valve - Commander Type (Pilot), Tank Blanketing
The DELCO ZZYVP-16 Self-operated Nitrogen Seal Valve (Commander Type) is engineered for precise nitrogen blanketing in storage tanks and reaction vessels. Operating without external power, this pilot-operated system utilizes the medium's energy to maintain a constant inert gas cushion. It effectively prevents oxidation, combustion, and evaporation loss, making it a critical safety component for chemical and petrochemical storage.
Features
A high-precision pilot-operated nitrogen blanketing valve requiring no external power, designed to maintain stable pressure in storage tanks for safety and oxidation protection.
✅Commander (Pilot) Precision: Unlike standard direct-acting valves, this Commander-type (Pilot-operated) design amplifies the feedback signal, allowing for extremely precise micro-pressure control, essential for delicate storage tanks.
✅Nitrogen Blanketing Protection: Automatically regulates nitrogen supply to create a protective gas seal, preventing hazardous media from contacting air. It pairs perfectly with [Breather Valves] to form a complete tank safety system.
✅Energy-Independent & Safe: Operates solely on the medium's pressure energy, requiring no electricity or compressed air. This intrinsic safety makes it ideal for explosion-proof zones where electrical sparks must be avoided.
✅On-the-Fly Adjustment: The pressure set-point is controlled by an adjusting spring on the commander, allowing operators to fine-tune the setting conveniently and continuously while the system is running.
✅Integrated System Design: Supplied as a complete assembly including the commander, fine needle valve, main valve, filter, and pressure reducing device, ensuring a robust and blockage-free operation for long-term reliability.
