stainless steel dry couplers are available for higher pressure ratings.

Reliable Sealing in Low-Temperature Environments

As temperatures drop, does your confidence in the sealing capability of API bottom loading couplings also decrease? In the past, the only way to resolve leakage in bottom loading couplings under low-temperature conditions—such as in northern regions during winter—was simply and frustratingly: wait for the temperature to rise. SOTUS introduces low-temperature sealing O-rings designed to withstand extreme cold conditions, maintaining oil resistance and wear resistance while meeting the challenges of freezing weather.提下应对极寒天气的挑战。

DCA-A Bottom Mounted Adapter (Unloading Valve)

Designed for tank truck bottom loading and gravity unloading, the DCA-A adapter complies with the API RP 1004 standard and is used in conjunction with API dry couplers. The adapter features a flat base to ensure complete drainage of liquid product during unloading. The two-stage fixed handle is ergonomically designed. The fluid-dynamically optimized design significantly reduces pressure drop and achieves high flow rates.

Valve Body Materials:

• Hard-anodized aluminum alloy

• Stainless steel

Preventing Product Leakage: When used in conjunction with the API dry coupler, the adapter effectively prevents product leakage during disconnection, reducing losses and environmental pollution.

Providing Reliable Sealing: The adapter itself has excellent sealing performance, preventing product leakage from the tank truck even when not connected to the API dry coupler.

Withstanding Tank Truck Internal Pressure: The adapter is capable of withstanding the internal pressure of the tank truck, ensuring no leakage or rupture occurs during loading and unloading operations.

Adapter Handle: With a limited opening angle, the adapter allows unloading and sampling without relying on the API dry coupler.
