HE010-150 Check Valve
HE010-150 is a DN150 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 external actuation, opening under forward flow and closing by spring force and reverse flow. The wafer body clamps between pipe flanges, requiring no additional flanges and adding minimal face-to-face length to the pipeline.

What This Model Gives You
- Automatic non-return operation eliminates the need for manual or actuated control
- Spring-loaded disc ensures rapid closure during reverse flow to prevent backflow
- Wafer body design reduces face-to-face length compared to traditional gate or globe check valves
- Clamps between existing pipe flanges, avoiding the need for extra flange pairs or welding
- Compact size allows installation in tight spaces where larger valves would not fit
- Built within a valve programme certified to ISO 9001 and ISO 14001
Problems It Removes
- Manual valves are not practical in systems requiring automatic backflow prevention
- Gate or globe check valves are too long and heavy for installations with limited space
- Lack of automatic closure leads to system damage or contamination during pump failure
- Mixed valve types on one project complicate spare parts inventory and maintenance
- Buyers need a single supplier offering both small and large diameter check valves in the same series
Where It Is Installed
- Prevention of backflow in pump discharge lines where power loss could cause reverse flow
- Installation in heating system circuits to maintain flow direction during pump cycling
- Use in water supply lines where backflow from a secondary source must be blocked
- Integration into low-pressure process piping where automatic isolation is required
- Application in sewage treatment plant flow control where manual valves are impractical
Buyers It Suits
- Pump and skid system builders needing automatic non-return valves in compact designs
- HVAC and heating engineers specifying space-saving check valves for system loops
- Water utility contractors sourcing reliable non-return valves for municipal distribution
- EPC firms standardising on automatic check valves across multiple project types
- Valve distributors stocking wafer-type check valves from DN10 to DN2600 in low- and medium-pressure ranges
How It Is Built
- Wafer body clamped between pipe flanges with through bolts
- Spring-loaded disc opens under forward flow and closes under reverse flow
- Automatic non-return operation with no handle, actuator, or operator required
- Disc movement guided by a central stem to maintain alignment during cycling
- Part of a HE010 wafer check valve series that continues through larger nominal diameters
- Designed for use in water, low-pressure process, and heating applications
Material Selection
- Body, disc, stem, and spring materials are confirmed per order based on the medium and operating temperature
- Material selection follows the variants offered across the HE010 wafer check valve series
- Material certificates are issued with the order upon request
How It Is Made
- Body casting inspected and machined on in-house fine machining equipment
- Disc, stem, and spring assembled as a matched unit with proper preload
- Valve body clamped and the disc set for free travel and spring tension
- Assembled valve tested for leak tightness and disc response 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
- Leak tightness test on the assembled valve under reverse flow conditions
- Disc travel and spring response verified on every unit during testing
- 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
- Disc and spring variant selected based on the medium and temperature on the buyer's line
- Flange drilling matched to the standard used on the buyer's pipework
- Private label marking and packing available on OEM orders
- Mixed-diameter orders combined with other valves in one container
- Material combination confirmed with the quotation and documented in material certificates
How It Compares With the Alternatives
| Lug type check valve | The lug body allows end-of-line service and dead-end isolation; the wafer body cannot |
|---|---|
| Gate valve with manual operator | The gate valve requires manual operation and is longer; the check valve operates automatically and is more compact |
| Spring-loaded globe check valve | The globe valve has higher pressure drop and is bulkier; the wafer check valve offers lower resistance and shorter length |
| Swing check valve | The swing valve has slower closure and larger footprint; the spring-loaded wafer valve closes faster and fits in tighter spaces |
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 aligned with the system direction
- 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 system flow direction remains consistent to avoid repeated disc slamming

HE010-150 Check Valve FAQ
What size and pressure rating is HE010-150?
It is a DN150 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 multiple variants.
Can this valve be used at the end of a pipe run?
No. A wafer body requires pipe flanges on both sides to clamp against. For 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. HE010-150 is an automatic non-return valve with no operator, handle, or actuator. It opens under forward flow and closes by spring force 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.
