Rotary Valve SRV

Features

■Standard Model
The upper and lower flanges of this valve conform to the standard specification.
The specification of flange can be selected from ANSI 150Lb,
DIN PN10, GB PN10, JIS 10K, however, the outer diameter and thickness of the flange will follow SHINIs standard.

■Main Materials
Casing: SCS 13 (stainless steel casting steel)
Side cover: AC4B-T6 (the design temperature is under 100℃)
SCS13 (the design temperature is over 100℃ or the air contacting part is required with stainless steel).

■Structure
Anti-shearing: in order to avoid chopping the pellet, the entrance of this valve is designed on the shape of  "W".
Shaft seal: use double-lip seal ring which material is PTFE to keep a higher sealing performance, without daily check necessary.
■Feed nozzle
SFN-type (T-type), applicable for the pneumatic conveying line with multi-station;
SFH-type (J-type), applicable for the dense phase pneumatic conveying which no powder remnant is allowable.
Vent chamber, Normally, the light powder is not fed to the rotary valve stably due to the leakage air. This vent chamber with special structure will help the rotary valve work properly.
 

Application

■ Plastic: virgin material & regrinding material.
■ Food: wheat, wheat powder, granulated sugar.
■ Mineral: coal, cement, etc.

Performance-Price Ratio

■ Rotary valves are made in China, but they are desi-gned by a Japanese engineer who had been working for 37 years in one Japanese factory, which is professional in producing air conveying equipments. Whats more, we imported Japanese checkup system based on our existing quality control system, which can ensure high quality machines.

Q & A

■ Q: Whats the driving way for rotor?
■ A: Rotor is driven by gear motor via chain wheel or chain bar. We also can change the rotating speed by manual gear motor or transducer (VVVF).

■ Q: How about the airproof feature of SRV?
■ A: Our SRV adopts high quality double-lip seal ring, the material is PTFE, which can endure causticity and with good airproof feature.

■ Q: How much pressure and differential pressure can be bared by SRV?
■ A: Standard pressure is 100kpa(1kgf/cm2), while it can bear differential pressure as about 60kpa.
