This water level gauge is suitable for various small pressure vessels and liquid storage containers, displaying the liquid level. The valve body material is HPb59-1 brass (forged), the sealing surface is made of copper alloy, cast iron handwheel, high borosilicate glass tube, etc. During installation, the external thread D1 of the water level gauge valve is consistent with the internal thread on the container. Due to the threaded connection of the valve body of this product, there are three different types of threaded connections available in one specification (see attached table for details).

Q: Could you offer the free samples ?
A: Yeah, but it depends products, Pls contact us ina@pneuhydr.com or whatsapp 0086 15168536055
Q: What ' s your business scope ?
A: Our business scope is service of exporter automation parts with full container, and sell air cylinder , air source treatment , solenoid valve , air valve, motorize valve , Brass valve, hydraulic valve, hydraulic cylinder, air and oil fitting, pressure gauge etc .
Q: What types of products you can make ?
A: We can make many kinds of stainless steel, brass ,aluminum materials processing .like high pressure Valve / solenoid valve / electric valve / water valve/pneumatic valve/air cylinder/hydraulic valve/hydraulic accumulator products and so on .
Q: Can the product be made with our logo and brand ?
A: Yes , of course , we can make . we are OEM supplier for years and professional to make . But you need give us the authorization if it is possible .
Q:Can you provide original famous pneumatic and hydraulic,instruments brand goods ?
A: Yes,We can supply like Festo,Smc,Ckd,Burket,Hydac,Rexroth,Siemens,Rosemount,Marsh ,Endress+Hauser etc.
Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc.
Q: What should be noted for pneumatic components in high temperature or extremely cold environments?
| Focus Point | High Temperature Environment Countermeasures | Extreme Cold Environment Countermeasures |
| Seals | Fluororubber, PTFE | Low-temperature nitrile, silicone rubber, polyurethane |
| Lubrication | High-temperature synthetic grease (low volatility) | Low-temperature grease (low pour point, low viscosity) |
| Air Supply Treatment | Strengthen cooling, efficient water removal | Ultra-low dew point drying (refrigeration + adsorption type), heat tracing |
| Metal Components | Reserve expansion clearance | Select materials with low-temperature toughness, prevent leakage due to cold shrinkage |
| Control Components | High heat-resistant grade coils, heat dissipation, low power consumption | Install insulation boxes, local heating, prevent cold condensation |
| Installation | Keep away from heat sources, add heat insulation plates | Avoid exposure to wind and snow, wrap with thermal insulation materials |
