Type 1112 butterfly valve can be used for any general applications and is a semilug butterfly valve. The body is 2 pieces and the disc and the stem is one piece.

Type 1120 is a concentrical butterfly valve and can be used for any general applications and is a semilug valve with 4 holes.

Type 4010 is a double flanged, double eccentrical valve and used as check valve. It ensures full tightness by elastomer-to-metal design (4010 S). Actuation types are hydraulic lever counter weight or with lever counter weight.

Type 4020 slanted seat check valve is a flanged double eccentric valve. It supplies full leakage tightness with metal-to-metal design and elastomer seated design. Actuation can be made with the internal damper unit. No lever and counterweight is required due to slanted design.

With the thin design of type 4310 , wafer check valves can be used to all general purpose applications. Easy installation and maintenance free. For bigger dimensions, the disc can be coated with elastomer.

Needle (plunger) valves are widely used in flow regulating or pressure control applications. Due to its special inner structure, flow cross section is always circular and it allows for precise control. Flow is always guided to the center of the pipe axis where bubbles from and recover without damaging the equipments in the line. Upstream and downstreams pressure and require flow rate defines the type of cavitation ring to be used. Ä°t is strongly recommed to have 10 x DN straight line upstream and downstream of the needle valve. Needle valves can be manuel operated electric actuated (on/off or modulating), hydraulic operated with counter weight depending on the application needs.

Type 7000 is good choice to be used for fibrous fluids such as paper industry and water treatment. Tightness is supplied with the PTFE seal. Actuation types are with gear box, handwheel, chainwheel and pneumatic or electrical. It has rising and non-rising stem alternatives.

7100 Type is a bi-directional valve to be used for fibrous fluids such as water treatment. With an undercut blade, it ensures that the deposits ın the liquid can be easily cleaned. Actuation types are with gear box, handwheel, chainwheel and pneumatic or electrical. İt has rising and non-rising stem alternatives.

Type 5010 is used for general applications, for easy mounting and dismounting of the flange armatures. Dismantling joint removes the stres on valves in the line due to installation problems. For each valve installation dismantling joint is recommended.

With its ethylene propylene based seat and deformation preventing steel ring, it is a long lasting sealing element. It can be used in the applications between the temperature of -40/+130 C by its asbestos free design.
