Valves for Heat Supply Pipelines
Heat supply networks rely on valves that maintain pressure and temperature stability across long runs of insulated pipe. We supply butterfly, gate, check and ball valves designed for throttling and regulating in heating systems, shipping from Tianjin as complete assemblies with actuators and joints.
What Goes Wrong on These Lines
- Valves that leak under thermal cycling damage insulation and reduce system efficiency
- Manual operation is impractical in buried or high-rise installations with limited access
- Throttling valves that wear quickly in hot water lose control accuracy over time
- Backflow from a pressure drop can cause water hammer and damage radiators or heat exchangers
- Mixed valve types across a network complicate maintenance and spare part management
What Buyers in This Sector Need
- Butterfly valves with resilient or metal seals that resist thermal expansion and contraction
- Gate valves with full bore design to avoid pressure drop in main supply lines
- Check valves that close quickly to prevent backflow after pump or boiler shutdown
- Actuators that operate reliably in temperature ranges from ambient to 150°C
- Documentation and marking that align with the utility's asset tracking system
Valve Families That Fit This Duty
Where the Valves Sit in the Plant
- Throttling control on primary heating loops in district heating substations
- Isolation valves on secondary circuits serving individual buildings or zones
- Non-return protection on boiler discharge headers to prevent reverse flow
- Expansion joint assemblies to absorb thermal movement in long pipe runs
- Dismantling joints for maintenance access without cutting the pipeline
From Line List To Delivered Container
You provide the schedule of sizes, pressures, and operating conditions and we assign the model code to each item
Body material, seat type, and actuation method are selected based on medium temperature and cycle frequency
You receive a line-by-line quote with confirmed specifications for each valve
Bodies, discs, stems, and seats are machined and assembled at our Tianjin plant
Shell strength, seat tightness, and full travel are tested and recorded before packing
The order is crated and loaded 50 km from Xingang seaport for container dispatch
Delivery Capability
- Mixed valve types consolidated into one container for single-lot delivery
- Marking and packing aligned with the buyer's asset numbering system
- Actuators fitted and pre-set before crating to eliminate on-site assembly
- Test records and material certificates issued upon request
- Fifty kilometres from Xingang seaport, about a sixty minute drive from the plant

Which valves are best for high-temperature hot water systems?
Butterfly valves with metal or high-temperature resilient seats and gate valves with heat-resistant body materials are suitable. Confirm the temperature and medium for exact model selection.
Can you supply actuators for remote control in a central heating plant?
Yes. Actuators are available for butterfly, gate, and ball valves and can be fitted before shipment. Specify the control type and voltage required.
How do you handle thermal expansion in long pipe runs?
We supply expansion joints and dismantling joints as part of the system. They are designed to absorb movement and allow maintenance without pipe cutting.
What certifications does the factory hold?
Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management certification. Additional approvals are confirmed before order.
What size and pressure range do you cover for heating systems?
Our valves cover nominal diameters from DN10 to DN2600 and nominal pressures from 0.05 to 4.0 MPa. Specific models are confirmed on request.
How do I get pricing for a full heating network project?
Send your valve schedule by WhatsApp or email. We return it marked with model codes and prices, usually within one working day.
