Vertical H-type Radiator Valve

Angle H-type radiator valve

Vertical H-type radiator valve adopts straight-through vertical H-block runner layout. The inlet and outlet keep co-axial straight routing, specially designed for bottom-in bottom-out radiators. It provides manual flow-regulation, branch shut-off and hydraulic balancing functions. No built-in check-valve function, no thermostatic wax capsule for auto temperature control. It is ideal when pipeline runs vertically straight without angle transition requirement.

Yuanlun vertical H-type radiator valve is brass manual straight-through H-block heating valve for hydronic heating systems. It features co-axial vertical H-shaped runner, perfectly matching bottom-in bottom-out radiator connection layout. Main assembly consists of valve-body, bonnet, valve stem, valve disc, valve seat and multi-group sealing-rings.

It supports three core manual functions: hot-water flow fine-tuning for hydraulic balancing, partial flow modulation and complete branch shut-off isolation for radiator overhaul. PN16 nominal pressure-rating, working-temperature 5℃-90℃. It can be applied for radiators, water distribution manifolds and floor-heating loop piping.

Important note: Installation recommended to be completed by qualified HVAC plumbing technicians. This valve is manual H-block valve, it has neither built-in anti-backflow check-valve nor automatic thermostatic wax capsule. Do not slam valve closed rapidly to avoid water-hammer damage. Thread joints need PTFE-tape auxiliary sealing.

• Straight-Through Runner Optimized for Bottom-In Bottom-Out Radiators: Vertical co-axial H-block flow-path matches vertical straight-connection radiators, eliminates extra elbow transition fittings, simplifies piping layout.
• Precise Manual Flow Regulation & Branch Shut-Off: Realize stepless flow adjustment for radiator heat-output and full shut-off for single-radiator maintenance, supports whole-system hydraulic balancing.
• Wide System Compatibility: Suitable for radiator circuits, heating water distributors, and floor-heating piping loops; adapts diversified residential and commercial hydronic heating-system requirements.
• Easy Installation & Simple Maintenance: Compact straight-through H-block structure. Standard thread interface, easy on-site assembly, inspection and component replacement, reduces labor time and maintenance expenditure.

Specifications

• Main Components & Function

• Operating Principle

Vertical H-type radiator valve relies on mechanical cooperation of valve-stem, valve-disc and valve-seat assembly to perform manual flow-control:

1. Rotate manual hand-wheel to drive valve-stem, which produces vertical stroke movement of valve-disc.
2. Flow-rate modulation: Adjust valve-disc opening degree continuously, change hot-water flow passing through radiator, fine-tune radiator heat-output and achieve system hydraulic balancing.
3. Branch shut-off isolation: Turn hand-wheel to fully close valve-disc against valve-seat, completely cut-off hot-water supply for single radiator branch. It allows radiator replacement or overhaul without shutting down the whole heating network.
4. Media flows in straight co-axial path without 90-deg direction shift, matching bottom-in-bottom-out radiator piping layout.

Operating reminder: This product is manual regulating H-block valve. It cannot automatically prevent reverse flow (no check-valve), and cannot auto-adjust temperature (no thermostatic capsule). Avoid violent rapid closing to prevent water-hammer shock.

• Bottom-In Bottom-Out Radiator Heating Circuits

Use-case: Straight-line vertical connection for radiators adopting bottom-in bottom-out interface in new-build or renovation heating-projects. Project value: Straight-through H-runner removes requirement for extra elbow adapters; keeps neat vertical pipeline routing.

• Heating Water Distribution Manifold Auxiliary Circuits

Use-case: Branch-circuit flow-regulation & shut-off for manifold-connected radiator loops. Project value: Supports independent branch isolation, convenient for single-loop commissioning and troubleshooting.

• Floor-Hydronic Heating Piping Loops

Use-case: Flow-balancing and local shut-off for floor-heating secondary circuits. Project value: Compatible with glycol anti-freeze heating-medium, satisfies residential & commercial HVAC project requirements.

• Pre-Installation Check

1. Confirm valve DN-size, thread-spec match radiator bottom-in-bottom-out port and on-site pipeline.
2. Inspect vertical H-block valve-body, bonnet, valve-stem, valve-disc and sealing-rings; reject cracked, deformed or damaged components.
3. Clean mating thread surfaces, remove burr, welding slag and old sealing-residue; prepare qualified PTFE-tape.

• Installation Steps

1. Wind PTFE-tape 3-5 clockwise-turns on mating radiator / pipeline thread.
2. Screw vertical H-type radiator valve onto radiator bottom-connection port; apply wrench torque only on valve-body flats. Do NOT apply wrench force on bonnet or manual hand-wheel.
3. Complete pipeline side connection; verify straight-through flow-path aligns with system design.
4. Rotate hand-wheel to test full-stroke open-close action; confirm valve-disc moves smoothly without jamming.
5. Fill heating-system with water and perform pressure-testing; inspect thread-joint and bonnet-stem sealing-position for leakage.
6. Execute initial commissioning: adjust valve opening-degree for radiator-branch hydraulic balancing.

• Important Installation Notes

1. Installation recommended for qualified HVAC plumbing technicians.
2. This valve has no built-in anti-backflow check-valve. If reverse-flow prevention is required, additional independent check-valve shall be installed in circuit.
3. No built-in thermostatic capsule; auto-temperature-control needs separate TRV thermostatic radiator valve.
4. Do not slam valve fully closed rapidly to avoid water-hammer shock damage to fittings and radiator.

Routine-Maintenance Suggestion

• Visual inspection for joint and stem-position leakage: Quarterly during heating-season
• Execute full-stroke open-close operation for each valve before heating-season startup: Annually
• Replace ageing sealing-rings upon seepage failure: As-required

When ordering vertical H-type radiator valve: confirm DN-size and thread-spec match bottom-in-bottom-out radiator port. Distinguish vertical straight-through H-block versus angle-type H-block radiator valve. Clarify project requirement: this product is manual regulating valve, without check-valve anti-backflow function and without auto-thermostatic function. If anti-backflow or automatic temperature-control is needed, order corresponding independent accessories / TRV thermostatic valve.
