Cast Iron Y-Strainer
Features & Standards of Metal-Seated Gate Valves
The flanged metal-seated cast iron gate valve is engineered to European standard EN 1171 for full isolation service in water transmission and pressurized mains. A robust cast iron body and precision-machined metal seating provide dependable shut-off.
The wedge operates perpendicular to flow via a manual handwheel, clearing the conduit bore completely to minimize hydraulic head loss in the fully open position.
Cast Iron Y-Strainer Filtration & System Protection
The cast iron flanged Y-strainer incorporates an internal stainless steel mesh screen within its angled leg to capture gravel, pipe scale, and suspended solid debris, safeguarding downstream meters and pump impellers.
The blow-off cover on the angled leg facilitates scheduled screen cleaning and sediment flushing without demounting the valve body from the pipeline.
Connection to Polyethylene Lines & Installation Guidelines
Bolting these valves into polyethylene piping networks utilizes a polyethylene stub end combined with a metallic backing ring (such as those in the pe-backing-rings category) and an elastomeric gasket.
Providing concrete support thrust blocks beneath heavy iron valve bodies prevents valve weight from exerting bending stresses on adjoining polyethylene lines.
Cast & Ductile Iron Valves — Frequently Asked Questions
Which products are active in the cast iron valves category?
Flanged metal-seated gate valves with manual handwheels and cast iron flanged Y-strainers are active in this section.
What standard governs the metal-seated gate valve?
The metal-seated gate valve is manufactured in accordance with European standard EN 1171 for cast iron industrial valves.
How are these cast iron valves joined to a polyethylene pipeline?
Via a polyethylene stub end fused to the pipe, clamped by a steel or ductile iron backing ring that bolts to the valve flange.
