A Tianjin valve manufacturer with several configuration routes
Tianjin Zhongfa Valve Co., Ltd., known as ZFA Valve, supplies butterfly valves with wafer, lug and flanged connections, alongside valve parts and other industrial valve families. For buyers, the useful starting point is the piping application: choose the connection and operating method together, then discuss the materials and model that fit the service.
The company's published catalog identifies its full name, Tianjin location and valve manufacturing business. Its current product pages give buyers direct routes into wafer and lug designs rather than a single, undifferentiated valve range.
Two butterfly valve families to start with
Wafer valves for a compact between-flange arrangement
A wafer butterfly valve fits between mating pipe flanges. ZFA's wafer range includes manually operated and actuated configurations, with different body, disc and seat options. Its catalog also shows lined designs, so buyers can discuss more than just the outside body material.
This is a useful product direction for a space-conscious water or HVAC piping brief. Send the fluid, operating conditions and flange details so the factory can propose a specific configuration. A compact body still needs room for the disc movement and operating equipment; use the proposed model drawing to check that layout.
Lug valves when the bolted connection is part of the brief
ZFA's lug range uses a body with lugs for the flange connection. The visible product selection includes lever, worm-gear and pneumatic examples, as well as different disc and seat combinations. This gives buyers a separate route when their specification calls for a lugged body.
If your project includes an end-of-line position, ask for the particular model's rated arrangement rather than choosing from the word “lug” alone. The company lists a pipeline-end product; its current drawing and service rating should be part of that discussion.
Build the enquiry around the job the valve will do
| Your project need | Configuration to discuss | Useful information to share |
|---|---|---|
| Local opening and closing | Manual operation: lever or gearbox, as offered for the selected model. | Installation space, access and required operating arrangement. |
| Remote operation | A complete pneumatic or electric valve assembly. | Available air or power supply, control signal, feedback and required loss-of-supply position. |
| A specified piping connection | Wafer, lug or flanged construction matching the project. | Flange standard, nominal size, mating-pipe details and layout drawing. |
| An OEM valve or branded product line | Customer-drawing manufacture or customization of an existing design. | Drawing revision, requested changes, marking, quantity and delivery destination. |
The table is a CNFX enquiry aid, not a model specification. For example, an equipment builder can describe a water skid needing remotely operated isolation, share the pipe connection details and ask ZFA to propose a valve-and-actuator package. This is an illustrative project brief, not a claimed customer installation.
From an existing model to an OEM project
ZFA describes two approaches in its OEM/ODM process: manufacture based on a customer's specifications or drawings, and customization based on existing designs. This is relevant both to equipment makers specifying a valve assembly and to distributors developing a defined product range.
Start by saying which approach you need. For a catalog-based order, identify the product and requested changes. For a drawing-based project, describe the intended function and available design information. Ask the factory to return the proposed configuration, drawing revision, sample arrangement and quotation scope together.
That makes the next step concrete: your team compares the proposed drawing and materials with the project brief, agrees any changes, and confirms what the sample or first delivery should demonstrate. Share confidential drawings only through an agreed channel.
Connect your project to CNFX product references
The following CNFX pages explain the related components. Their general parameters are not specifications or performance promises for a ZFA model.
| Product reference | Use in your project conversation |
|---|---|
| Butterfly Valve | Define the flow-isolation component and discuss the body connection and selected materials. |
| Pneumatic Actuator | Explain an air-operated assembly requirement; ask ZFA to match the actuator to the valve and service. |
| Valve Actuator | Clarify the desired operating and control arrangement before requesting a complete package. |
Once you have the component vocabulary, send the application brief to ZFA through its factory profile. You can request a model proposal without copying a generic catalog's numerical ranges.
Buyer questions
What is the difference between wafer and lug butterfly valves?
The principal distinction here is how the valve body connects between pipe flanges. A wafer arrangement is clamped between mating flanges; a lugged body provides lug connection points. Specify the actual flange and service arrangement so the selected model fits the project.
Can I order an actuated valve rather than a bare valve?
ZFA's wafer and lug listings include actuated examples. Describe whether you need local or remote operation and ask for a complete matched assembly. The actuator selection should follow the selected valve and operating duty, not only the pipe diameter.
What information makes a quotation easier?
Include fluid, temperature and pressure conditions, size, connection, operation, quantity and destination. Three common omissions are naming a seat material without the fluid, giving a nominal diameter without the flange specification, and asking for automation without the control requirements.
Does one product family cover every application?
No. Material compatibility, operating limits and any required approvals are specific to the proposed model and service. Discuss those details with ZFA while selecting the product; this spotlight is not an installation procedure or a certification assessment.
Start with your application, then choose the valve
Whether you need a wafer valve, a lugged configuration or a customized assembly, introduce the piping duty and desired operating method. ZFA can then respond to a defined product request rather than a generic “valve price” enquiry.
