HE010-300 Check Valve
HE010-300 is a DN300 wafer type check valve designed for automatic unidirectional flow control in water, heating, and low-pressure industrial pipelines. It operates without external actuation, relying on the differential pressure across the valve to open and close the disc. The wafer body clamps between two pipe flanges, eliminating the need for separate valve flanges and reducing installation space and cost.

What This Model Gives You
- Automatic operation requires no manual or actuated intervention once installed
- Wafer body design reduces face-to-face length and weight compared to flanged valves
- Clamps between existing pipe flanges, avoiding the need for welding or extra flanges
- Bidirectional flow prevention ensures system integrity during pump stoppage or reverse flow
- Low pressure drop when fully open, maintaining flow efficiency in continuous service
- Part of a check valve programme certified to ISO 9001 and ISO 14001
Problems It Removes
- Manual valves require constant attention and are prone to human error during pump cycling
- Flanged check valves add length and weight to the pipeline, increasing installation cost and space use
- Lack of automatic operation leads to system damage from reverse flow during pump failure
- Inconsistent valve types across a project increase spare parts and maintenance complexity
- Buyers need a single supplier for both small and large diameter check valves in the same series
Where It Is Installed
- Preventing backflow in pump discharge lines after pump shutdown in water supply systems
- Protecting heat exchangers and boilers from reverse flow in district heating networks
- Maintaining flow direction in closed-loop cooling systems in power and industrial plants
- Isolating sections of pipeline during maintenance without manual valve operation
- Ensuring one-way flow in sewage treatment plant pump stations where flow reversal is hazardous
Buyers It Suits
- Water utility engineers specifying automatic isolation valves for pump stations
- HVAC and heating system designers needing compact check valves for tight spaces
- Pump skid builders integrating automatic check valves into pre-fabricated units
- EPC contractors sourcing reliable, low-maintenance check valves for medium- and low-pressure systems
- Valve distributors stocking wafer check valves across a range of nominal diameters
How It Is Built
- Wafer body clamped between two pipe flanges using through bolts
- Disc pivots on a central stem to open and close under flow differential
- Resilient seat provides tight shut-off and minimizes wear during repeated cycling
- Automatic operation triggered by forward flow; closes when flow reverses or stops
- Part of the HE010 wafer check valve series covering DN10 to DN2600
- Designed for use in water, heating, and low-pressure industrial services
Material Selection
- Body, disc, stem, and seat materials are confirmed per order based on the operating medium and temperature
- Seat material options follow 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 and stem assembled with pivot and seat fitted for smooth travel
- Valve tested for free movement and automatic closure under simulated reverse flow
- Assembled unit pressure tested and checked for leakage before packing
- 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
- Seat tightness and shell integrity tested on the assembled valve
- Automatic operation and disc 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
- 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
- Optional actuator or manual override can be added if required for specific applications
How It Compares With the Alternatives
| Flanged check valve | The flanged version has longer face-to-face length and higher weight, but can be used in dead-end service where wafer bodies cannot |
|---|---|
| Lug type check valve | The lug type allows end-of-line installation and can be removed without disconnecting both pipes, unlike the wafer body |
| Wafer check valve with spring assist | The spring-assisted version closes faster under reverse flow but adds cost and complexity; HE010-300 relies on flow dynamics for closure |
| Ball check valve | The ball check valve offers tighter shut-off at higher pressure but has a higher pressure drop and is less suitable for large diameters |
Installing and Operating This Valve
- Confirm the flange standard and bolt pattern on both pipe flanges before ordering
- Install the valve with the arrow on the body aligned with the flow 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 ensure the body seats squarely
- Do not use the wafer body as a pipe end closure during pressure testing
- Periodically cycle the valve on lines where it remains in one position for long periods to prevent seat adhesion

HE010-300 Check Valve FAQ
What size and pressure rating is HE010-300?
It is a DN300 valve in the HE010 wafer check valve series. The pressure rating and flange standard 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?
No. A wafer body requires 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 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 a different flange standard?
Yes. Flange drilling can be matched to the standard used on your pipework, such as ANSI, DIN, or JIS, when confirmed during the quote.
Do you supply the larger diameters in the same series?
Yes. The HE010 wafer check 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.
