Explosion-proof solenoid valve safety, applicability

Safety
Corrosive medium: plastic king solenoid valve and all stainless steel should be used; for strong corrosive medium, isolation diaphragm type must be used. Example CD-F. Z3CF. For neutral medium, it is also advisable to choose a solenoid valve with copper alloy as the valve housing material, otherwise, rust will often fall off in the valve housing, especially in occasions where the action is not frequent. Ammonia valves cannot use copper.
Explosive environment: products with corresponding explosion-proof grade must be selected, and waterproof and dust-proof varieties should be selected for outdoor installation or dusty places.
The nominal pressure of the solenoid valve should exceed the maximum working pressure in the pipe.
applicability
1. Select different types of solenoid valves for gas, liquid or mixed state, for example, ZQDF is used for air, ZQDF-Y is used for liquid, ZQDF-2 (or -3) is used for steam, otherwise it will easily cause malfunction. ZDF series multi-function solenoid valve can pass through gas and liquid. It is best to inform the state of the medium when ordering, so that the installation user does not need to adjust.
2. Products with different specifications for medium temperature, otherwise the coil will burn out and the seals will age, which will seriously affect the lifespan.
3. Medium viscosity, usually below 50CST. If it exceeds this value, ZDF series multi-functional solenoid valves are used for special orders if the diameter is greater than 15MM. Order a high viscosity solenoid valve with a diameter less than 15MM.
4. When the cleanliness of the medium is not high, a recoil filter valve should be installed in front of the solenoid valve. When the pressure is low, a direct-acting diaphragm solenoid valve can be used as CD-P.
5. If the medium is directional flow, and reverse flow is not allowed, ZDF-N and ZQDF-N only need to use two-way flow, please make a special request.
6. The medium temperature should be selected within the allowable range of the solenoid valve.
