DIN F4 gate valve is mainly divided into NRS non-rising stem and RS rising stem (OS&Y). The main material is ductile iron. When the whole rubber-coated valve plate is closed, the deformation compensation effect achieves a good sealing effect, which overcomes the poor sealing and water leakage of general gate valves. and rust

Confirm the medium, pressure and temperature conditions, size, selected body and trim materials, connection standard, stem arrangement and operating method before ordering.
FAQ
What DIN F4 flange information is required?
Provide the existing flange standard, nominal size, facing, bolt pattern and required face-to-face dimension. Ask for a matching valve drawing; the DIN F4 description should not be used by itself to approve flange or installation compatibility.
What should be confirmed for the resilient-seated NRS arrangement?
Check the proposed drawing for the non-rising-stem arrangement, operator access and maintenance clearance. Confirm the actual resilient-seat material and the selected assembly’s operating limits against the intended medium and service conditions.
Which medium and material details are needed before ordering?
State the fluid composition, operating and design conditions and any project material restrictions. Request the exact body, gate, stem and resilient-seat materials in the quotation, with supporting material documentation where required.
