Rising stem resilient gate valve

The valve body is constructed from high‑strength ductile iron with great overall rigidity and long‑lasting durability. The fully rubber‑encased wedge delivers excellent soft‑sealing capacity to accomplish zero‑leakage shut‑off.
Its groove‑free flat‑bottom cavity resists sediment and dirt build‑up, effectively preventing valve sticking and operation failure. Boasting an unobstructed flow‑passage for low hydraulic resistance, the valve permits bidirectional water flow and requires no specified installation orientation.

Detail

Parameters

This rising‑stem resilient‑seated gate valve is suitable for water‑supply, sewage and waste‑water pipelines.

Designed with a rising‑stem structure, its stem moves up and down while opening and closing. The exposed stem height visually

indicates the valve position, which makes status inspection convenient on‑site and permits the installation of extended handles or

electric actuators.

Constructed of high‑strength ductile iron, the wedge is fully rubber‑coated for tight bubble‑tight shut‑off. Its flat‑bottom cavity avoids

sediment buildup and seal‑face jamming.

The straight‑through passage creates low flow resistance. Bidirectional sealing removes installation‑direction limits. Its stainless‑steel

stem and brass drive nut deliver smooth operation. Multiple rubber seal options provide heat‑resistance and ageing‑resistance, well‑

suited for exposed pipelines, pump stations and municipal drainage networks.

• Exposed rising stem provides real-time visual position indication for quick on-site management.
• Pocketless full straight bore keeps fluent flow, lowers head loss, and prevents internal sediment build-up.
• Integral rubber-encapsulated wedge realizes adaptive resilient sealing and permanent bi-directional zero leakage.
• Light torque operation and pipeline-non-dismantling maintenance reduce later operational costs remarkably.
• Robust multistep ductile iron yoke ensures long service life and enables fast on-site assembly.
