Industrial valves for water, power, and process pipelines
Butterfly, gate, check valves and pipe joints from Tianjin MIC Valve Co., Ltd. Medium- and low-pressure catalog, established 1998.
Specify a valve set from one Tianjin maker
Pipeline contractors, water utilities, and industrial buyers who need medium- and low-pressure butterfly, gate, check, and joint products for water, power, chemical, heat-supply, and process lines.
The problem
Specify and source a complete valve set—from wafer butterfly valves to resilient-seated gate valves, dual-plate checks, and expansion joints—from one Tianjin manufacturer instead of stitching multiple catalogs.
Why buyers contact MIC
Operating since 1998 in Jinnan, Tianjin, near Xingang seaport. Published catalog of 227 models. Company states ISO 9001 and ISO 14001. Named export sales contacts on WhatsApp and email. Hong Kong entity VOC International Industry Limited for offshore trade.
What to send
Send the DN, pressure rating, connection type, and medium on WhatsApp to Sara Ma or Lockon Wong for a quotation.

Where these valves are specified
Valves for Water Supply and Drainage
A water line needs a matched set: isolation (butterfly or resilient seated gate), non-return (check or foot valve), and often a dismantling joint so the valve can be pulled in a chamber.
Valves for Power Generation Auxiliary Systems
Power-plant auxiliary water systems need isolation and check valves that match existing flange standards and operator preferences (gear or actuator), not a one-size lever.
Valves for Petroleum and Chemical Pipelines
Unlined iron valves are the wrong default when the medium attacks the body or seat. The catalog’s anti-corrosive and PTFE-seat butterfly listings exist for that duty; ratings still have to be confirmed per medium.
Valves for Heat-Supply Networks
Heat-supply water needs isolation valves and expansion joints that match the network’s DN and flange drill. Seat material must suit the circulating-water temperature—confirm it on the quote.
Valves for Shipping Auxiliary Systems
Marine projects often need compact wafer or lug valves plus confirmation of coating and material. The live site does not publish class certificates—ask sales for the documents the project requires.
Valves for Pharmacy Utilities and Metallurgy Water Systems
These plants still run large volumes of cooling water, process water, and drainage. The same butterfly, gate, check, and joint families apply; lined or stainless trim is a quoting item, not a published default.
