- Outline Dimensions & Weight (Typical values – may vary by manufacturer)
Dimension Parameter | Value (Typical non-rising stem brass gate valve) |
Valve Length (end-to-end) L | Approx. 55 – 65 mm |
Thread Size (BSPT) | 1/2″ (DN15) female taper |
Handwheel Diameter | Approx. 50 – 60 mm |
Overall Height (closed position) H | Approx. 80 – 100 mm |
Valve Weight | Approx. 0.3 – 0.4 kg |
Dimensions above are typical references. Final dimensions may vary by manufacturer; confirm with actual product or drawing.
- Pressure-Temperature Rating (Brass body)
Temperature (°C) | Max. Working Pressure (bar) | Teguran |
-10 ~ 50 | 16 (PN16 rating) | Ambient |
100 | 10 | |
120 | 7 | |
150 | 4 | |
Note: Brass valves are generally suitable for temperatures ≤150°C. Above 120°C, pressure must be significantly derated. PTFE packing has a maximum service temperature of approx. 150°C.

Air Seat Test Pressure | 6 bar |
Allowable Differential Pressure | Full rated pressure (gate valves not recommended for throttling) |
Leakage Rate | Metal seated: Minimal leakage (API 598 allowable) PTFE coated seat: Zero leakage |
Julat Suhu | -10°C ~ +120°C (standard) |
Suitable Media | Water, oil, gas, non-corrosive media |
Jenis Injap | Non-rising stem wedge gate valve (normally uni-directional) |
- Ciri-ciri Utama
- Brass body – Good corrosion resistance and machinability; suitable for water and low pressure steam
- BSPT taper thread – Reliable sealing, easy installation; no need for additional sealing tape
- Non-rising stem design – Compact construction, ideal for space‑limited installations
- Full bore or reduced bore – Typically reduced bore (slightly lower flow capacity than pipe size)
- Low operating torque – Light handwheel operation
- Cost effective – Widely used in construction, HVAC, water supply and drainage
- Installation & Operation Instructions
- Thread connection – Apply PTFE tape or thread sealant to BSPT male threads. Screw in clockwise. Do not over‑tighten to avoid cracking the valve body.
- Flow direction – Gate valves generally have no flow direction restriction, but it is recommended to install with the arrow (if marked) or horizontally.
- Operasi – Turn handwheel clockwise to close, counter‑clockwise to open. Valve should be fully open or fully closed; not suitable for throttling (may erode sealing surfaces).
- Maintenance – If stem leakage occurs, carefully tighten the packing gland nut. If leakage persists, replace the packing.
