Wafer Type Dual Plate Check Valves

HE010-50 Check Valve

HE010-50 is a DN50 wafer type check valve designed for automatic non-return service in water, low-pressure fluid and air 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, requiring no additional flanges or welding. It is part of a valve programme covering DN10 to DN2600 and 0.05 to 4.0 MPa, with over 600 models produced in-house.

Key Benefits

What This Model Gives You

  • Automatic operation eliminates need for actuators, levers or manual intervention
  • Wafer body clamps between existing flanges, reducing installation cost and space
  • Spring-assisted closure ensures fast shut-off on reverse flow or pump stop
  • Compact face-to-face length fits tight spaces where gate valves would not
  • Bidirectional flow control with no external control required
  • Part of a certified valve programme with ISO 9001 and ISO 14001 compliance
Problems Solved

Problems It Removes

  • Manual isolation valves require extra operators or actuators, increasing cost and complexity
  • Gate valves are too long and heavy for tight spaces between flanges
  • Lack of automatic closure leads to backflow damage in pump systems
  • Mixed valve types on one project increase spare parts inventory and maintenance effort
  • Buyers need a single supplier for both isolation and check valves across different diameters
Application Scenarios

Where It Is Installed

  • Preventing backflow in pump discharge lines on water supply systems
  • Protecting pumps from water hammer in low-pressure heating circuits
  • Maintaining flow direction in gravity-fed water headers in industrial plants
  • Isolation of auxiliary lines in power plant auxiliary systems where automatic shut-off is required
  • Non-return service in chemical process lines with low to medium pressure
Who It Is For

Buyers It Suits

  • Water utility engineers specifying automatic check valves for pump stations
  • HVAC and heating system designers needing compact non-return valves
  • Pump and skid system builders integrating automatic isolation into fixed frames
  • EPC contractors sourcing reliable check valves for multiple projects
  • Valve distributors stocking a wafer check valve range from DN50 upward
Technical Features

How It Is Built

Customisation

What Can Be Changed

  • Disc and spring variant selected for 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 variants confirmed during quotation
Comparison

How It Compares With the Alternatives

Lug type check valveThe lug body allows end-of-line service; the wafer body requires flanges on both sides
Gate valve with manual operationThe gate valve requires a handle or actuator and is longer; the check valve operates automatically and is more compact
Ball valve with manual operationThe ball valve requires a handle or actuator and is more expensive; the check valve is automatic and lower cost for non-return duty
Butterfly check valve with discThe butterfly check valve has a larger disc and higher pressure drop; the HE010 has a smaller disc and lower flow resistance
Use Guide

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
  • Do not use the wafer body as a pipe end closure during pressure testing
  • Ensure the disc can move freely before tightening the through bolts
  • Avoid installing in horizontal runs with low flow where sediment may settle and jam the disc
  • Inspect the valve periodically in systems where it remains in one position for long periods
FAQ

HE010-50 Check Valve FAQ

What size and pressure rating is HE010-50?

It is a DN50 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 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.

Can it be supplied with a different spring or disc type?

Yes. The disc and spring variant are selected based on the operating medium and temperature, and confirmed during the quotation.

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.
