Bronze Seat Gate Valve — Rising Stem
Model: Z41T-10 / Z41T-10C — Rising stem · bronze wedge sealing · water & utility lines
Gaoshan’s rising-stem bronze-seated gate valve, offered in gray cast iron (Z41T-10) or cast steel (Z41T-10C) body for tight, reliable shut-off on general water and utility service. The exposed stem lets you visually confirm open/closed position at a glance, and the bronze wedge seals directly against a bronze seat ring for long-term drip-tight closure.
Typical Industries
– Municipal & industrial water – HVAC & building services
– General plant utility lines – Irrigation & water supply
Specifications
| Pressure class | PN16 (indicative — confirm by size) |
|---|---|
| Max temperature | ≤135°C |
| Body material | Gray cast iron or cast steel |
| Connection | DN40 and up, flanged (RF) |
| Stem type | Rising stem, handwheel operated |
Bronze Seat Gate Valve — Non-Rising Stem
Model: Z45T-10 / Z45T-10C — Non-rising stem · bronze wedge sealing · water & utility lines
The non-rising stem counterpart to the Z41T-10, offered in gray cast iron (Z45T-10) or cast steel (Z45T-10C) body. The stem stays flush within the bonnet as the valve opens, making it the better fit for installations with limited overhead clearance or where an exposed rising stem would be exposed to damage.
Typical Industries
– Underground & buried service – Confined mechanical rooms
– General plant utility lines – Water supply networks
Specifications
| Pressure class | PN16 (indicative — confirm by size) |
|---|---|
| Max temperature | ≤135°C |
| Body material | Gray cast iron or cast steel |
| Connection | DN40 and up, flanged (RF) |
| Stem type | Non-rising stem, handwheel operated |
Resilient Seated Gate Valve
Model: Z45X — Rubber-wedge sealing · zero-leakage shut-off · water & wastewater networks
A fully rubber-encapsulated wedge seals against the valve body with no metal-to-metal contact in the waterway, giving true zero-leakage (Class VI) shut-off with low operating torque. This is the standard choice for municipal and underground water/wastewater projects where long, maintenance-free service life matters.
Typical Industries
– Municipal water distribution – Wastewater treatment
– Fire protection systems – Underground / buried service
Specifications
| Pressure class | PN10 / PN16 |
|---|---|
| Max temperature | ≤80°C (water service) |
| Seat material | EPDM or NBR rubber-encapsulated wedge |
| Connection | Flanged (RF) or socket, DN50 and up |
| Leakage class | Class VI (zero leakage) |
Motor-Operated Gate Valve
Model: Z941H (hard seal) / Z941Y (soft seal) — Electric actuator · remote & automated shutoff
The wedge gate is driven by an integral electric actuator instead of a handwheel, letting the valve be opened, closed, or interlocked remotely from a control room or PLC. Suited to process lines, pump stations, and pipelines where manual operation is impractical or too slow for emergency isolation.
Typical Industries
– Petrochemical process units – Pump stations & pipelines
– Power plant utility systems – Remote / unmanned installations
Specifications
| Pressure class | PN16 – PN25 |
|---|---|
| Operation | Electric actuator (manual override available) |
| Wedge type | Solid wedge (Z941H) or resilient wedge (Z941Y) |
| Connection | Flanged (RF) |
| Control | Local switch or remote/PLC signal |
Gas Plate Gate Valve
Model: RZ47F (flanged) / RZ43F (threaded) — Parallel slide plate · city gas & low-pressure gas lines
Purpose-built for city gas and low-pressure gas pipeline shutoff, using a parallel-slide plate design for tight bidirectional sealing without the friction wear of a wedge design. Widely used by gas utilities for main-line and service-line isolation.
Typical Industries
– City gas distribution – Gas utility service lines
– Low-pressure gas pipelines
Specifications
| Pressure class | PN10 / PN16 (low-pressure gas) |
|---|---|
| Body material | Ductile iron or cast steel |
| Connection | RZ47F flanged / RZ43F threaded |
| Sealing | Parallel slide plate, bidirectional |
Z41T-10 vs Z45T-10 vs Resilient Seated vs Motor-Operated
Choose the right gate valve type for your operating conditions.
| Feature | Z41T-10 (Rising Stem) | Z45T-10 (Non-Rising Stem) | Resilient Seated (Z45X) | Motor-Operated (Z941H/Y) |
|---|---|---|---|---|
| Seal Type | Bronze-to-bronze wedge | Bronze-to-bronze wedge | Rubber-encapsulated wedge | Solid or resilient wedge |
| Stem | Rises visibly above bonnet | Stays flush within bonnet | Rising or non-rising | Actuator-driven |
| Leakage class | Tight shut-off | Tight shut-off | Class VI (zero) | Depends on wedge type |
| Operation | Handwheel | Handwheel | Handwheel | Electric actuator |
| Best for | Open installations, easy visual check | Limited overhead clearance, buried service | Municipal water & wastewater | Remote / automated isolation |
Body Materials
| Material | Temp Range | Typical Use |
|---|---|---|
| Gray Cast Iron | ≤135°C | Water, general utility |
| Ductile Iron | ≤120°C | Water, gas, wastewater |
| Cast Steel (WCB) | ≤425°C | Steam, oil, process lines |
| Stainless Steel | -29°C ~ 425°C | Chemical, corrosive media |
