Astam’s Super Lite has been especially developed as an alternative product of a conventional swing check which does not require fully open condition for the piping that swing check valves are installed and not require to be fully opened. Since it is lightweight and compact compared to the conventional type it can save maintenance and processing costs.

Characteristics of Super Lite

• • Simple design :
    Super lite is constructed of only five pieces. O-ring made of general-purpose material such as NBR, FPM, and PTFE is attached to a seat ditch of the body. Those O-rings are replaceable.
  • Lightweight :
    Our Super Lite is an ideal compact check valve. Since this is wafer type, it is installed by inserting between the companion flanges and tightened by bolts.
  • Easy installation :
    It is easy to install thanks to a short face-to-face. Since the outside diameter of Super Lite is equal to the inscribed circle of installation bolts, the installation work is efficient and economical. Any specific installation support is unnecessary.

Characteristics of Super Lite

Cautions for installation

・Please make sure to install the valve in a horizontal condition. Then L-bolts of the valve should be in a vertical to ground and upward condition.
・Please use welding flanges of JIS10K for the exit side flange.

Overview:

Two semi-circular plates are mounted to the valve body by a hinge pin. When the fluid flows, each plate opens in a V shape centering on the hinge pin and fully opens up to the stop pin.

Kinds of Super Check Valve

C1 type (standard type) resilient seat

There is no leakage at the time of closing by vulcanized rubber bonded on the valve body seat.

C1 type (standard type) metal seat

Each seat of the valve body and plates is metal to metal, therefore, it can prevent the reverse flow under the condition of more high temperature・high pressure.

C０ type (O-ring in plate groove)

FPM O-ing is attached to the plate’s seat, and it can seal perfectly even at extremely low counter pressure (Counter pressure of 2,000mmAq for a horizontal position. *Order Production

C2 type (Check valve with a by-pass valve)

A by-pass valve is attached to the valve body. At the time of stopping the pump, by opening a stop valve of the by-pass, it is possible to drain the water of the downflow side. *Order Production

C3 type (Flanged type)

The valve body and flanges are cast all in one dody. This C3 type is used for the piping of a poisonous gas or flammable gas, or in case it is concerned about the expansion and contraction of the piping bolts with the temperature change. *Order Production

C5 type (Shock resistant check valve)

Please use this type if the opening shock of the fluid is huge. The plates of the valve and pins are designed to be tougher than normal products. This structure tolerates severe conditions and can be used long-term by appropriate maintenance. *Order Production
