Valves for Water Supply and Drainage Pipelines
Water supply and drainage networks rely on isolation and non-return points that must function after long periods of inactivity. We supply butterfly gate valves, check valves, and associated components from our Tianjin factory, delivering complete packages with actuators, joints, and strainers for direct installation.
What Goes Wrong on These Lines
- Valves that remain in one position for years seize when required to open or close
- Limited space in buried chambers prevents access for manual operation or valve removal
- Backflow after pump failure causes surge damage and contaminates the main supply
- Grit and debris in raw water degrade rubber seats and obstruct valve movement
- Multiple valve brands across a network prevent shared spare parts and standardised maintenance
What Buyers in This Sector Need
- Full bore resilient seated gate valves that maintain flow efficiency and seal reliably after long inactivity
- Compact butterfly valves with short end-to-end dimensions for tight spaces in pump stations
- Automatic check valves that close rapidly to limit pressure surge following pump trip
- Dismantling joints allowing valve removal without cutting or disturbing the pipeline
- Clear documentation and consistent marking matching the utility’s asset management system
Valve Families That Fit This Duty
Where the Valves Sit in the Plant
- Sectioning valves on distribution mains and district metered areas for maintenance access
- Isolation and non-return protection on pump suction and discharge lines in booster stations
- Surge control on pump discharge headers to prevent backflow and system damage
- Strainer and expansion joint assemblies protecting pumps, meters, and pipeline runs
- Square and circular gate valves for flow control in sewage treatment plant channels
From Line List To Delivered Container
You provide the schedule of sizes, duties, and standards; we assign the model code to each item
We confirm seat material, body pattern, and actuation method based on the medium and operating cycle
You receive a model-by-model price with the confirmed specification for each valve
Bodies, discs, and stems are machined and matched; valves are assembled at our Tianjin plant
Shell and seat tightness, and full travel are tested and documented before packing
The order is crated and loaded 50 km from Xingang seaport for container dispatch
Delivery Capability
- Multiple valve types consolidated into one container for single-lot project 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 provided with shipment on request
- 50 kilometres from Xingang seaport, approximately a 60-minute drive from the factory

Which valves do you recommend for a buried sectioning chamber?
Resilient seated gate valves are standard due to full bore, soft seat sealing, and key-operated operation from ground level. For short chambers, wafer or lug butterfly valves with gearboxes are suitable.
How do you handle raw water with grit and rag?
We recommend gate valves or lug butterfly valves with harder seat materials. A strainer upstream of pumps and meters is advised. Provide water details and we will confirm the seat.
Can you supply joints and strainers with the valves?
Yes. Expansion joints, dismantling joints, and strainers are produced at the same plant and ship in the same container as the valves.
What certification 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 sizes can you cover on a network project?
Our range spans DN10 to DN2600 and 0.05 to 4.0 MPa across over 600 models, enabling supply of both service connections and trunk mains from one source.
How do I get pricing for a whole scheme?
Send the valve schedule in any format via WhatsApp or email. We return it marked with model codes and prices, typically within one working day.
