Oliver Twinsafe produces a range of Trunnion Ball and Floating Double Block and Bleed Valves. We offer true double isolation with two independent ball valves contained in one valve body, guaranteeing absolute shut-off and maximising the safe operation of any processing facility.

To answer the growing demand of reliable and robust metal-seated threaded & welded ball valves, our experienced engineering teams designed the JBSM Series, meeting the requirements of the most challenging industries: Oil & Gas, Refineries, Petrochemical & Chemical Industries, Power Generation, Pulp

Trunnion ball valves have the obturator bounded by trunnions which do not allow axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball, the contact between surfaces generates the valve sealing; trunnion standard construction ensure automatic cav

Forged trunnion ball valves are an excellent choice for on/off service in large and high pressure applications because the ball is anchored at the top and bottom of the design. Bonney Forge is a trunnion mounted ball valves manufacturer in an extensive range of designs, materials, sizes, pressure cl

Bonney Forge is a leading check valve supplier. Piston and ball check valves, like all forged steel check valves, are used to prevent back flow in the line. Standard valve design has no spring in order to minimize cracking pressure and pressure drop, it will only function properly when installed in

A large trunnion design ensures central positioning under the highest working pressure. Independent floating spring loaded seats provide a tight seal even at low differential pressures. Service and maintenance is simplified with a bolted body design incorporating double o-rings or a combination of o

Trunnion mounted ball valves are engineered for high-pressure systems and large sizes. The ball is fixed in place, reducing torque and seat wear. Widely adopted by European valve manufacturers for critical pipelines. Our stock valves offer unmatched reliability with prompt delivery. Partner with top

The Series S85 Threaded Ball Valve complies with various standards and certifications, including ISO 5211, NACE MR0175, NSF-61/372, ASME B16.34, MSS-SP-72, MSS-SP-110, PED, PE(S)R, CRN, and SIL.

Floating ball valves are ideal for low to medium pressure applications where tight shutoff is crucial. The ball floats slightly downstream to press against the seat, ensuring a reliable seal. Trusted by top European valve manufacturers, these valves offer simplicity and efficiency. As leading ball v

The Series S70/S90 Threaded Ball Valves are designed to comply with MSS-SP 72 and tested to comply with MSS-SP 72. The design standard is MSS SP-110.
