2 Valve Manifold Engineered to the specific designs for low, medium and high-pressure usage. The Needle Valves & Manifolds manufactured by General Instruments are available in a wide range of materials and designs. Based on specific client requirement, we can design different models meeting critical process applications.

Designed and manufactured based on ASTM / DIN / BS and other relevant standards depending on the client requirements.

Manufactured from forged Stainless Steel – ASTM A 479, ASTM A182 F304, ASTM A182 F316, ASTM A182 F304, ASTM A182 F304L, Carbon Steel – ASTM A 105, Monel, Inconel, Hastelloy, Titanium, other on request. Material with NACE compliance is available.

The gland sealing arrangements used in General Manifolds vary with the temperature requirement. The most common is PTFE for temperature upto 180 Deg C however for temperature above 180 Deg C to 270 Deg C graphitized asbestos is a common gland seal. Beyond 270 Deg C and upto 540 Deg C, graphoil can be offered.

Test / Certificates : Certificate of conformance, Test certificate, Material test certificates, 3.1 MTC, 3.2 MTC, PMI, NACE-MR-01-75 & NACE-MR-0103, Hydrotest, etc. available.
