UNIWAT 630W are Y-type pipeline strainers designed for mechanical retention of solids in water networks. They feature a removable perforated stainless steel basket accessible via the cover. Typical installation points include upstream of pumps, control valves, water meters, heat exchangers, and HVAC equipment to reduce ingress of sludge, rust, or particulates into the system.
Standard version is PN16, with EN 1092-2 type 21/B flanges and EN 558 S1 / DIN 3202 F1 face-to-face length. Suitable for fresh water and neutral liquids (group 2 per PED 2014/68/EU). For NBR: TS -10 to 80°C; for EPDM: up to 110°C (general design).
Standard perforation: 1.2 mm for DN40–50, 1.6 mm for DN65–150, 3.1 mm for DN200–300. Selection should consider flow rate, Kvs, allowable pressure drop, and fouling rate. For pump suction, vacuum, high velocities, or water hammer, reinforced screens may be required.
Basket must not be positioned at the top of the pipe. Horizontal installation or vertical flow downwards is preferred, following the flow arrow. Allow space for cover removal, screen cleaning, and use of the drain plug.
Design: EN 12516; Marking: EN 19; Testing: EN 12266-1; PED 2014/68/EU up to Category I. Declaration of conformity covers flanged Y-strainers UNIWAT 630W, PN16, DN15–600. WRAS certificate validity should be confirmed in the current WRAS listings for potable water use.
Actuator compatibility?
No. This is a passive in-line strainer; actuators are not applicable.
When to select EPDM?
For water applications requiring EPDM compatibility and higher temperature limits than NBR.
Suitable for steam?
Not as standard. Documentation covers water and neutral group 2 liquids only.
Y-Strainers PN16 with perforated basket for mechanically removing solids from flowing media and protecting equipment. Basket replaceable in line and drain plug. Epoxy coating internal and external.
Specification of the range:
Diverse design combinations by materials of construction, nominal size range (DN40-DN600) and filtration passage.
Other typical denominations: Y strainers epoxy coated
