Steam Jacketed Backpressure Regulators

High-Viscosity Pressure Control | Engineered & Assembled by Inacom Instruments

Maintain Process Integrity with the Inacom Steam Heated Backpressure Solution The Inacom Steam Jacketed Backpressure Regulator is a premier, custom-engineered solution specifically developed for high-viscosity pressure control in demanding international process environments.

Where standard regulators fail due to media cooling or solidification, our design ensures a constant thermal environment. By integrating a high-performance GO Regulator® or Swagelok® core into a proprietary, high-grade stainless steel steam jacket, we provide a system that eliminates condensation, crystallization, and product fouling.

Technical Features & Inacom Engineering

Unlike standard off-the-shelf components, the Inacom Steam Jacketed Regulator is an in-house engineered assembly designed for long-term reliability in EPC and OEM projects worldwide.

• Proprietary Steam Jacket Design: A fully encapsulated housing (Ø 10.5 cm) providing uniform heat distribution across the entire regulator body.

• Precision TIG-Welded Construction: Every jacket is assembled using Tungsten Inert Gas (TIG) welding. This electric arc process ensures a high-strength, lifetime bond between the steam jacket and the regulator body, capable of withstanding rigorous industrial cycles.

• Extended Port Architecture: To ensure ease of installation, the internal 1/4” NPT ports (Inlet, Outlet, and Gauge) are extended via stainless steel pipe sections. This aligns all process and steam connections on a single plane outside the jacket wall.

• High-Viscosity Optimization: Specifically ported to handle non-Newtonian fluids, high-solid content, and media that must remain at a stable temperature without the use of electrical heating.

• Universal Compatibility: Seamless integration with industry-standard backpressure technology.

How it Works: Superior Thermal Uniformity

The Inacom Steam Jacketed Regulator is engineered for maximum heat transfer efficiency. Unlike traditional heat-tracing or external blankets that often leave “cold spots,” our system utilizes a fully integrated Stainless Steel heating jacket.

The Thermal Block Principle: Saturated steam is introduced through a dedicated 1/4” NPT inlet and circulates throughout the jacket. This transforms the regulator into a single, uniform thermal block. By maintaining the process media at a consistent temperature from inlet to outlet, the risk of product solidification on the valve seat is eliminated.

Key Technical Advantages

• Elimination of Cold Spots: The full-jacketed design ensures 360-degree thermal coverage, preventing local temperature drops that cause product build-up.
• Rapid Thermal Response: Direct steam-to-body contact allows for faster heat-up times compared to convective or radiant heating methods.
• High-Durability Construction: The entire jacket is manufactured from high-grade Stainless Steel, providing excellent resistance to corrosion and industrial cleaning agents.
• Process Stability: By maintaining fluids in their optimal liquid state, the system prevents erratic pressure spikes caused by fouling or partial blockages.
• Reduced Maintenance: Prevents the “gumming up” of internal components, significantly extending the service life of diaphragms and seals.
• Zero-Leak Path Design: The steam circuit is completely isolated from the process media, ensuring no cross-contamination.

A Legacy of Expertise: Since the 1980s

The Inacom Steam Jacketed Regulator was born from necessity. In the early 1980s, Inacom Instruments developed the first $500$ psi stainless steel heated backpressure regulator to solve critical cooling issues in ethylene analyzers.

Decades of refinement have turned this into a “popular-demand” solution for any application where gas or liquid must be held at a precise temperature to prevent phase changes or polymerization.

Target Media & Applications

• Polymer & Resin Processing: Pressure control for PET, PA, adhesives, and melts.

• Hydrocarbons: Bitumen, waxes, paraffins, and heavy syrups.

• Chemical Recycling: Managing pyrolysis oil and recycled streams.

• Analyzers: Pre-heating or temperature stabilization for gas chromatography and sampling systems.
