SoliValve® Double Cone System

Name: HECHT SoliValve® Double Cone System
Brand: HECHT

Emptying

OEB Level 5

Description

The SoliValve® double cone system from HECHT enables fully automatic, low-contamination and closed containment emptying and dosing (up to AGW / OEL 10 - 100 µg/m³) of less hazardous products. Special big bags with sealing cones (SoliBag®) are used.
In contrast to other bulk material handling solutions available on the market, SoliValve® is a versatile and reliable technology with outstanding results and strong performance in terms of containment (OEB5), dosing accuracy (+/-1g) and complete automation.
The unique technology and functionality as well as the universal passive SoliValve design guarantee smooth filling and emptying of big bags, containers, drums or sacks through one and the same docking unit.
Expensive and complicated double butterfly valves or the old-fashioned cone valve technology, which requires the connection of proprietary big bags, are now obsolete: SoliValve® is more than just a new cone valve system, but a standard for a completely new technology.

Frequently asked questions about the SoliValve double cone system

What is SoliValve and why is double-cone architecture revolutionary?

SoliValve is a double-cone isolation system for zero-spill product transfer. Double-cone architecture is revolutionary because: (1) it eliminates dead-leg <2mL, (2) it provides redundant failsafe closure, (3) it delivers zero product loss, (4) automatic pneumatic closure means zero manual risk.

How much product loss occurs with SoliValve?

Zero product loss. Double cones close hermetically. Dead-leg <2 mL (minimal). Zero-spill transfer interface. Perfect for batch segregation and containment.

How does the double-cone isolation system work?

Two pneumatic cones close sequentially: (1) the inner cone shuts off product flow, (2) the outer cone isolates the inlet. Redundancy means: if one cone fails, the other prevents spillage. Pneumatic actuation = no manual handling.

Is SoliValve GMP-compliant?

Yes. GMP Annex 1 (2022) compliant, GAMP 5 validation standard. FDA 21 CFR Part 11 logged pneumatic cycles. EU GMP grade. Flow characterisation available.

What transfer speeds does SoliValve work with?

Up to 50 L/min (adjustable). Variable flow control per product viscosity. Zero product loss regardless of speed.

What is the advantage of zero dead-leg?

Zero product contamination risk between batches. Zero carry-over to the next batch. Zero manual cleaning required. Perfect for multi-batch scenarios and critical OEB 2–5 operations.

How reliable is SoliValve?

Very reliable. Redundant double-cone design = failsafe architecture. Pneumatic actuation = no moving parts (no mechanical wear). Validated for continuous operation of 5+ years without maintenance.

How much maintenance does SoliValve require?

Minimal. Monthly pneumatic pressure check. Annual sealing inspection. Corrosion-resistant stainless steel cone. Very reliable design.
