HE010-200 Check Valve
HE010-200 is a DN200 wafer type check valve with a spring-loaded disc, designed for automatic non-return service in water, low-pressure process and heating lines. It operates without manual input, opening under forward flow and closing by spring force and reverse flow. The wafer body clamps between two pipe flanges, eliminating the need for separate valve flanges and reducing face-to-face length in tight installations.

What This Model Gives You
- Automatic non-return operation requires no operator, handle or actuator
- Spring-loaded disc closes quickly on reverse flow to prevent backflow
- Wafer body clamps between existing flanges, reducing installation cost and space
- Short face-to-face length allows compact layout in pump skids and pipe racks
- Bidirectional flow protection with no manual intervention needed
- Part of a check valve programme certified to ISO 9001 and ISO 14001
Problems It Removes
- Manual isolation valves are not practical in systems requiring automatic backflow prevention
- Longer valves like gate valves take up too much space between flanges in retrofit projects
- Lack of automatic closure leads to damage from reverse flow during pump failure
- Mixed valve types on one project complicate spare parts inventory and maintenance
- Buyers need a single supplier for both small and large diameter check valves in the same series
Where It Is Installed
- Prevention of backflow in pump discharge lines where power failure could cause reverse flow
- Protection of water supply systems from contamination during pressure drops
- Isolation in heating circuits where reverse flow could damage heat exchangers
- Automatic shut-off in low-pressure process lines during pump stoppage
- Installation in tight spaces between flanges where a gate valve would not fit
Buyers It Suits
- Water utility engineers specifying non-return protection in pump stations
- HVAC contractors installing check valves in heating and cooling loops
- Pump skid builders needing compact, automatic isolation in fixed frames
- Plant maintenance teams replacing failed check valves with a standardised wafer type
- EPC buyers sourcing automatic non-return valves for water and low-pressure systems
How It Is Built
- Wafer body clamped between two pipe flanges with through bolts
- Spring-loaded disc opens on forward flow and closes on reverse flow
- Automatic operation with no handle, lever or actuator required
- Disc movement guided to maintain alignment and reduce wear
- Part of a HE010 wafer check valve series that continues through larger nominal diameters
Material Selection
- Body, disc and spring materials are confirmed per order against the buyer's medium and temperature
- Disc and spring variants follow the options offered across the HE010 wafer series
- Material certificates are issued with the order when the buyer requests them
How It Is Made
- Body casting inspected and machined on the in-house fine machining equipment
- Disc and spring assembled and tested for free movement and spring force
- Valve body fitted with disc and spring, then set for correct closing pressure
- Assembled valve tested for automatic opening and closing under flow reversal
- Marked, wrapped and crated for container shipment from Tianjin
How It Is Checked
- Dimensional check of body face-to-face length and flange bolt pattern before assembly
- Flow reversal test to confirm automatic closure and disc movement
- Spring force verified on every unit to ensure consistent closing speed
- Testing carried out on the 10 sets of imported inspection and testing equipment
- Records kept 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
- Disc and spring variant selected for the medium and pressure on the buyer's line
- Flange drilling matched to the standard used on the buyer's pipework
- Private label marking and packing on OEM orders
- Mixed-diameter orders combined with other valves in one container
- Material combination confirmed with the quotation and documented on request
How It Compares With the Alternatives
| DN200 resilient seated gate valve | The gate valve provides a full bore but requires manual operation and is longer and heavier |
|---|---|
| Lug type check valve | The lug body allows end-of-line service and dead-end isolation; the wafer body cannot |
| Wafer check valve with no spring | The non-spring version relies on flow reversal alone to close, which may be slower and less reliable |
| Ball valve with check function | A ball valve with check feature is more complex and costly; the spring check valve is simpler and more reliable for low-pressure non-return |
Installing and Operating This Valve
- Confirm the flange standard and bolt pattern on both pipe flanges before ordering
- Install the valve with the flow arrow pointing in the direction of forward flow
- Leave the disc slightly open while inserting the valve between flanges to avoid seat damage
- Tighten the through bolts evenly in a cross pattern to seat the body squarely
- Do not use the wafer body as a pipe end closure during pressure testing
- Ensure the line is free of debris before installation to prevent disc jamming

HE010-200 Check Valve FAQ
What size and pressure rating is HE010-200?
It is a DN200 valve in the HE010 wafer check valve series. The pressure rating and flange standard are confirmed against your line data when we quote, since the same body is offered in more than one seat and drilling variant.
Can this valve be used at the end of a pipe run?
No. A wafer body needs pipe flanges on both sides to clamp against. For dead-end or end-of-line service ask for the lug type body instead.
Which materials are used for the body, disc and spring?
Material selection depends on the medium and temperature on your line, so we confirm the combination with the quotation and issue material certificates with the order on request.
Does it require an actuator or handle?
No. The HE010-200 is an automatic non-return valve with no operator, handle or actuator. It opens on forward flow and closes by spring and reverse flow.
Do you supply the larger diameters in the same series?
Yes. The HE010 wafer check valve range 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.
