Application Engineering
Break-to-open torque, safety factors and stem sizing reviewed against your P&ID and valve datasheet — with ISO 5211 / 5210 flange recommendations.
Industry Solutions · ISO 5211 / API 6D
From municipal water networks to offshore platforms and hydropower penstocks — we engineer worm gear operators and bevel gearboxes matched to your valve type, torque duty and environmental class. ISO 5211 compatible mounting, 100% torque-tested delivery.
Integrated Approach
We align torque sizing, flange interface, materials and protection rating to your process conditions — then validate every unit on calibrated benches before shipment.
