Wafer check valve RSK 00 Advantage corrosion resistant simple installation as a wafer type flange fitting centring of the valve by the housing diameter body with O-ring, no additional flange s required space saving, maintenance-free design for vertical or horizontal mounting Version Wafer check valve without return spring for vertical pipes. Wafer check valve with return spring for horizontal pipes. Spring accessories. We also recommend this type for pulsating flow conditions. Utilisation for regulation of a prescribed flow direction - backflow preventer Flow Media Neutral and aggressive fluid or gaseous media, provided that the valve components coming into contact with the media are resistant at the operating temperature in accordance with the ASV resistance guide. Contaminated media may impair the function. Nominal Pressure (H O, 0 C) PN - PN Closing Pressure hermetically sealed at 0, bar Opening Pressure see table Fluid Temperature see pressure/temperature diagram Operating Pressure see pressure/temperature diagram Size DN 0 - DN 00 Body PVC-U PP PVDF Shut-Off Disc PVC-U PP PVDF Sealing FPM PTFE EPDM easy-to-install ASV installation adaptors on the outlet side on the inlet side with flange adaptors or welding stubs according to DIN ISO with flat jointing faces Attention Ensure that the valve disc makes contact with the inner wall of the fitting before it reaches the max. opening angle, otherwise there is a risk of breakage. Mounting vertical or horizontal, please note the direction of the arrow on the valve housing Flow Direction always in the direction of the arrow Option installation adaptor Accessories Spring made of stainless steel (.7) or Hastelloy (C) Colour body: PVC-U, grey, RAL 70 body: PP, grey, RAL 70 body: PVDF, opaque, yellowish-white > data sheet no.: 00-0/0/ ASV Stübbe GmbH & Co.

Wafer check valve RSK 00 Pressure/temperature diagram Pressure loss curve (standard values for H O, 0 C) P = pressure loss Q = flow pressure loss and k v value The diagram shows the pressure loss P in relation to the flow Q. Conversion aid: c v = k v x 0.07; f v = k v x 0.0 Units: k v [l/min]; c v [gal/min] US; f v [gal/min] GB Installation note P = operating pressure T = temperature The pressure/temperature limits are applicable for the stated nominal pressures and a computed operating life factor of years. These are standard values for harmless media (DIN 0), to which the valve material is resistant. For other media please refer to the ASV resistance guide. The durability of wear parts depends on the operating conditions of the application. For temperatures below 0 C (PP < +0 C) please specify the precise operating conditions of the application. The rated pressure depends on the valve and material. For the corresponding rated pressure value of the valve, please refer to the»order table«. = ASV installation adaptor > data sheet no.: 00-0/0/ ASVStübbe GmbH & Co. KG Hollwieser Str.

Wafer check valve RSK 00 RSK: Opening pressure pressure (mbar) without spring Flow direction: from bottom to top FRSK: Opening pressure (mbar) with spring Flow direction: from bottom to top Operating note Safe operation of the valve can only be ensured if it is properly installed, operated, serviced or repaired by qualified personnel according to its intended use while observing the accident prevention regulations, safety regulations, relevant standards, directives/technical regulations or codes of practice such as e.g. DIN, DIN EN, DIN ISO and DVS*. *DVS = German Welding Society The intended use includes adhering to specified limit values for pressure and temperature, as well as checking the resistance. This requires all components coming into contact with the medium to be "resistant" in accordance with the ASV resistance guide. > data sheet no.: 00-0/0/ ASV Stübbe GmbH & Co. KG Hollwieser Str.
