DLA002 Lug Butterfly Valve Carbon Steel Hand Lever
DLA002 is a lug type butterfly valve made from carbon steel with a hand lever, designed for on-off and throttling service in medium- and low-pressure industrial pipelines. It features threaded lugs on the body that allow installation at the end of a pipe run or in dead-end configurations where flanges are not present on both sides. The carbon steel construction provides durability in water, heating, and general industrial service lines.

What This Model Gives You
- Lug body allows installation at the end of a pipe run or in dead-end service where flanges are not present on both sides
- Carbon steel body offers strength and resistance to moderate corrosion in water and low-pressure industrial media
- Hand lever enables manual quarter-turn operation for quick isolation or throttling
- Lug design simplifies maintenance by allowing removal of the valve without disconnecting the entire pipeline
- Part of a valve programme covering DN10 to DN2600 and 0.05 to 4.0 MPa, with over 600 models available
- Built within a factory certified to ISO 9001 and ISO 14001 for consistent quality and environmental control
Problems It Removes
- Wafer valves cannot be used at the end of a pipe run because they require flanges on both sides
- Lack of a reliable end-of-line isolation valve leads to downtime during maintenance
- Inconsistent valve types across a project increase spare parts inventory and complexity
- Manual operation is needed in areas without compressed air or electrical power for actuators
- Buyers need a single supplier who can provide both small and large diameter valves in the same series
Where It Is Installed
- Isolation of water supply lines in municipal heating systems where the valve is installed at the end of a run
- Throttling control in low-pressure cooling water circuits in power plants and industrial facilities
- End-of-line service in petrochemical process piping where flanges are not available on both sides
- Maintenance access in sewage treatment plant pipelines using the lug design for easy removal
- Retrofitting into existing pipe runs where space or flange availability limits the use of wafer valves
Buyers It Suits
- Procurement engineers sourcing carbon steel butterfly valves for industrial water and heating systems
- EPC contractors standardising on lug type valves for end-of-line isolation in multiple projects
- Plant maintenance teams needing valves that can be removed without disconnecting the entire pipeline
- Valve distributors stocking a range of lug butterfly valves from DN10 upward for diverse applications
- Design engineers specifying a valve that can be used in both dead-end and in-line configurations
How It Is Built
- Lug type body with threaded lugs for bolting to pipe flanges at one end
- Carbon steel body suitable for medium- and low-pressure service
- Quarter-turn hand lever for manual operation
- Resilient seat for bidirectional sealing in water and similar media
- Designed for use in DN10 to DN2600 nominal diameter range with pressure ratings from 0.05 to 4.0 MPa
- Part of a product programme with over 600 models and multiple variants across families
Material Selection
- Body, disc, stem, and seat materials are confirmed per order based on the medium and operating temperature
- Seat and disc options follow the variants offered across the DLA lug series
- Material certificates are issued with the order upon request
How It Is Made
- Body castings inspected and machined on in-house fine machining equipment
- Disc and stem assembled and tested for alignment and movement
- Seat fitted and closure member set for consistent sealing
- Valve assembled and pressure tested before packing
- Marked, wrapped, and crated for container shipment from Tianjin
How It Is Checked
- Dimensional checks of lug position and flange bolt pattern before assembly
- Seat and shell tightness tested on the assembled valve
- Operating torque and full quarter-turn travel verified on every unit
- Testing performed on the 10 sets of imported inspection and testing equipment
- Records maintained under the ISO 9001 quality management system
Certificates Issued With This Valve
- ISO 9001 quality management system certification
- ISO 14001 environmental management system certification
Certification statements are limited to the management system certificates the factory actually holds. Product-level approvals for your market are confirmed before order.
What Can Be Changed
- Seat and disc variant selected based on the medium and temperature on the buyer's line
- Hand lever, gearbox, or actuator fitted before shipment upon request
- Flange drilling matched to the standard used on the buyer's pipework
- Private label marking and packaging available on OEM orders
- Mixed-diameter orders combined with other valves in one container
How It Compares With the Alternatives
| Wafer type butterfly valve | The wafer body requires flanges on both sides; the lug body can be used at the end of a pipe run |
|---|---|
| Lug butterfly valve with actuator | The hand lever version is lower cost and simpler for manual operation; the actuated version suits automated systems |
| Gate valve at DN100 | The gate valve offers a full bore but is heavier and longer; the lug butterfly valve is more compact and lighter |
| Ball valve at DN100 | The ball valve provides tighter shutoff at higher pressure but costs more and requires more clearance for the handle sweep |
Installing and Operating This Valve
- Confirm the flange standard and bolt pattern on the pipe before ordering
- Ensure the pipe end is clean and free of burrs before installing the valve
- Tighten the lug bolts evenly in a cross pattern to avoid misalignment
- Open the disc fully after installation and confirm free quarter-turn travel
- Do not use the valve as a pressure test plug during hydrostatic testing
- Cycle the valve periodically if it remains in one position for extended periods to prevent seat sticking

How To Choose Between Wafer and Lug Butterfly Valves
The body style decides whether the valve can hold the line on its own. Here is how to pick without guessing.
DLA002 Lug Butterfly Valve Carbon Steel Hand Lever FAQ
What size and pressure rating is DLA002?
It is a lug type butterfly valve in the DLA series. The nominal diameter and pressure rating are confirmed against your line data when we quote, as the same body is offered in multiple variants.
Can this valve be used at the end of a pipe run?
Yes. The lug body design allows installation at the end of a pipe run or in dead-end service where flanges are not present on both sides.
Which materials are used for the body, disc, and seat?
Material selection depends on the medium and temperature on your line. We confirm the combination with the quotation and issue material certificates with the order on request.
Can it be supplied with an actuator instead of a hand lever?
Yes. The stem can be fitted with a gearbox, pneumatic, or electric actuator, and the valve is assembled and tested with the actuator before shipment.
Do you supply the larger diameters in the same series?
Yes. The DLA lug butterfly valve series continues through the larger nominal diameters, and our valve programme covers DN10 to DN2600 across all families.
What certification does the factory hold?
Tianjin MIC Valve Co., Ltd. is certified to the ISO 9001 quality management system and the ISO 14001 environmental management system.
