Valves &
Fittings
Twelve valve and fitting lines in bronze, brass, forged and stainless steel, supplied to DIN, BS, ANSI and API pressure classes — with trim selected against the media rather than against a catalogue page.
DeltaGBS sources industrial valves and pipe fittings — gate, globe, ball, check and butterfly valves, strainers, flanges and forged fittings in bronze, brass, cast iron, carbon and stainless steel — with material certificates and pressure test reports.

Complete Valve & Fitting Supply, One Source
Delta GBS supplies a complete range of industrial and construction valves, flanges, strainers and expansion joints to contractors, EPC firms, MEP consultants and trading partners worldwide — a single point of procurement for complex project bills of material.
Live Mechanism Schematics
Gate Valves
NRS & OS&Y full-bore isolation, bronze/brass/forged stainless. DN15–DN300 · PN10–PN25, Class125/150.
Globe Valves
Standard, bellow-sealed & Y-type throttling control. DN15–DN250 · PN16–PN40, Class125/150.
Check Valves
Swing, lift & wafer styles preventing backflow. DN15–DN300 · PN16–PN40, Class125/150.
Butterfly Valves
Lug & wafer bodies for large-diameter lines. DN50–DN600 · PN16, lever or gear operated.
Ball Valves
Bronze & stainless, full-bore low-torque shut-off. DN15–DN150 · screwed or flanged ends.
Strainers
Y-type & basket-type with removable screens. DN15–DN300 · PN16–PN40, perforated or wire mesh.
Balancing Valves
Manual flow-balancing & metering valves with a calibrated setting scale and pressure test ports, so commissioning engineers can verify and lock in design flow rates across every branch of a hydronic circuit.
- Sizes DN15–DN200
- Ratings PN16 / PN25
- Materials bronze, brass
- Calibrated dial & test ports
Rubber Flexible Joints
Fabric & wire-reinforced rubber bellows absorb axial compression, axial extension and angular deflection between pipe sections and rotating equipment, shielding the system from vibration, noise and fatigue.
- Inner/outer rubber — NR, NBR, EPDM, PTFE
- Reinforcing cord — nylon tire cord
- Reinforcing ring — hard steel wire
- Flange — Q235 / SS304 / SS316
SS Flexible Joints
Corrugated stainless-steel bellows absorb axial compression, axial extension, lateral offset and angular rotation in a fully welded, leak-tight envelope — torsion is the one movement the bellows should never be asked to take.
- Sizes DN25–DN600
- Rating PN16 / Class 150
- Flanged or butt-weld ends
- Optional flow liner, cover & tie rods
Air Release Valves
A float rises and falls with the water level inside the body — venting trapped air through the orifice when air collects, then sealing automatically as water lifts the float. On draining, the same float drops to admit air and break the vacuum, preventing headloss, flow reduction and structural damage at high points, long runs and mainline valves.
- Sizes DN25–DN200
- Rating PN16
- Single, double orifice & water hammer types
- Body — cast iron, carbon steel, stainless
Flanges
A bolted, gasketed connection between the raised faces lets systems be disassembled for inspection or maintenance without cutting the line — the two faces mate to seal, then part again on demand.
- Sizes DN15–DN600
- Ratings PN10–PN40, Class150/300
- Raised face or flat face
- Material — carbon / stainless steel
Gas Service Joints
Ball-type shutoff valves engineered for the tap where a service line branches off the distribution main toward a building's gas meter — tight, dependable quarter-turn shut-off for natural gas and LPG over long service intervals.
- Sizes DN15–DN150
- Rating PN16 / Class 150
- Body — carbon steel / bronze
- Service — natural gas, LPG

Sourced to Project Specification
Sizes, end connections, trims and pressure classes beyond the standard range shown here can be sourced to project specification. Contact Delta GBS technical sales for full datasheets, certification and lead times.
What Happens After You Enquire
Four stages, with a checkpoint at each one where you approve before we proceed.
Specification Review
We come back with clarifying questions on grade, standard, tolerance and destination before quoting anything.
Sourcing & Quotation
Matched to qualified mills across three sourcing regions, quoted with incoterm, lead time, packing and payment terms in full.
Production & Inspection
Production slot booked on confirmation, progress updates issued, third-party inspection arranged at your instruction.
Shipping & Documents
Loading photographs before sealing, then the full document set couriered or presented through your bank as agreed.
