SS304/316 Stainless steel lug butterfly valve

Stainless steel lug butterfly valve with handle operation

JRVAL specialized in stainless steel material lug type butterfly valve production, which have been focusing on stainless steel material butterfly valve production over 15 years, with over 300 customers from home and aborad.

Products featurers:

1) The valve stem bearing use "copper sleeve", which with good wear and corrosion resistance. Although cost is 50% higher than other materials, prolong the service life by 60-70%;

2) Rubber seat contains over 50% rubber, with stable resilience and tension. Although the cost is 30% higher than that of similar products in the market, its service life can be extended by 1-2 years; valve seat option with PTFE, NBR, EPDM, FKM etc.

3) Material of worm gear includes gray iron, ductile iron, stainless steel, aluminum alloy, etc;

4) Based on different valve size and differnet opening torque, worm gear includes small torque, medium torque, large torque, single gear, double gear, tripple-gear etc;

5) With Different settings can be customerized, such as: Worm gear+r+indicator, worm gear+solenoid, worm gear+bracket, worm gear+ Siemens electric controller, worm gear+ indicator light and other configurations are avialable.

2）Details Introduction

1. Valve body & disc casting

A. Automatic wax mould machine makes wax pattern production with high efficiency, saves time also guarantees wax pattern without deformingï¼›

B. Automatic pulp mixer is used for shell making , the slurry is fully and evenly stirred, which makes the shell stronger, and valve body without air hole after casting;

C. Steam boiler is used for automatic de-waxing, which makes the inner cavity of the shell is clean and neat, guaranteed highly work efficiency.

D. Spectrum analyzer test each batch of valve body, ensures valve body meet with standard.

2. Machining

The machining workshop is equipped with over 20 kinds of machine tools, such as general lathe, vertical lathe, boring machine, drilling machine, etc., ensures the processing of valve bodies with different materials and sizes;

3. Assemble

Strictly control the assembly process, take every detail seriously, prevent leakage and achieve high quality valve.

4. Inspection

Different size valves equipped with special pressure testing machines, makes valve sealing performance test accurate and effective.

6. Quality & Service Warranty

1) Material: We analyze the materials of valve body and disc with spectrometer, issue material test report to customers;

2) Pressure: We proceed pressure test to ensure pressure test reaches 18kg (International standard 16kgs);

3) Packing: We use plastic bubble bag, paper box and plywood box triple packing, to ensure valve surface is not scratched and does not move during transportation;

4) Transportation: To avoid the impact of bumps and bad weather during transportation, van type trucks are used for transportation and distribution;

5) Installation guidance: We provide remote service and installation guidance, free arts are available during warranty period;

6) Technical support: We provide 7 * 24 services; Refer urgent issues, we guarantees prompt response within 24 hours and provide solution within 72 hour.
