Inlet Valve Cross Piece 4"-1/4" MNPT with Shower Head only (No fittings)

This inlet end cap valve is precision-engineered from 304 stainless steel and comes equipped with a shower head that ensures even fluid distribution across the material column—helping to reduce dry spots and promote consistent flow.

It comes standard with a ¼” female NPT welded ball valve, also constructed from 304 stainless steel. Please note: the ball valve requires a separate fitting to attach a hose. If you don’t already have this fitting, it can be purchased separately.

Users have the option to attach a pressure gauge, allowing them to monitor the internal pressure within the material column during operation.

This unit is designed to work in conjunction with a recovery tank. The third port is multi-functional and is typically used either for vacuuming the material column or for introducing nitrogen into the system from above.

Benefits of Upgrading to This Inlet Cross Assembly:

• Enables integration of nitrogen

• Supports direct vacuum evacuation from the material column

Why Use Nitrogen?

Nitrogen plays an essential role in closed-loop fluid systems. It allows fluid transfer at subzero temperatures without the need to apply heat to the recovery tank. This enhances the dewaxing process and results in a clearer, higher-purity extract.

As nitrogen accumulates in the system, pressure will increase—especially at low temperatures—so regular bleeding is necessary. This can typically be done from the recovery tank or the base.

Vacuuming from the Material Column

Vacuuming from the column itself is a crucial feature for anyone running multiple processing cycles. It allows the operator to disconnect and reload the material column while the system is still in recovery mode—saving time and reducing workflow interruptions.

There’s no need to disassemble the entire setup. Botanical Health Oils Hardware Ltd. systems excel in this area, offering unmatched efficiency and convenience.

When the column is reattached, the system must be re-evacuated. This cannot be done from the base, which is often filled with residual fluid. Instead, vacuuming must be done through the hose running back to the recovery tank and through the material column, all the way down to the ball valve connecting to the base.

This is essential for two key reasons:

1. Safety – Air trapped in the system can pose a hazard during pressurised operation.

2. Purity – If air is not fully removed, the application of dry ice may cause condensation inside the column, disrupting filtration and reducing extract quality.
