Angle seat valves made of gunmetal & stainless steel

M&M International Angle Seat Valves are available in red brass (CB491K EN 1982) and stainless steel (AISI 316L / CF3M) The seals used are exclusively PTFE (TFM 1600) and FKM. Connections include threaded connections (ISO 228/1), NPT threads (ANSI / ASME), clamp couplings (ISO 2852 and ASME BPE), flange connections (ANSI B16.10 Class 150 and EN 1092 Form B) and weld-on ends (ISO 658). ANSI B 36.10).

function types

Angle seat valve NC (normally closed) - Flow over the valve seat:The control medium opens the valve. The spring closes it. The flow of the process medium takes place above the valve seat.

Angle seat valve NO (normally open) - Flow under the valve seat:The control medium closes the valve. The spring opens the valve. The flow of the process medium takes place under the valve seat.

Angle seat valve Double acting - Flow above or below the valve seat:The control medium opens and closes the valve. There is no spring. Two 3/2 way Pilot solenoid valves are needed. The flow of the process medium thus takes place either above or below the valve seat.

Angle seat valve Bidirectional - flow above or below the valve seat:the control medium opens the valve. The spring closes it. There are two springs available. The flow of the process medium thus takes place either above or below the valve seat.

Positioning function

The inclined seat control valve manufactured by M & M is actuated by a compact pneumatic built-in positioning function, which operates in a closed circuit. The switch point signal (transmitted from the control board) is compared with the control feedback signal of the positioning function. If these 2 values do not match, the positioning function activates 2 microvalves (which open or close the valve) until the values match. The proportionality between valve lift and torque flow is ensured by the special design (linear or equal percentage). When the valve is completely closed, the hydraulic seal is additionally secured by another seal, as is standard in standard M & M angle seat valves.

Conversion kit position indicator

Conversion kit suitable for all M & M angle seat valves. Thus, a position indicator (magnetic or inductive) can be installed on the top of the control head. It transmits an electrical signal showing the open position of the valve. The function should not be confused with the positioning function, which shows the exact open or closed position of the valve. The sensor is not included in the conversion kit. The conversion kit is suitable for magnetic or inductive sensors with threaded bodies with a maximum outer diameter of 12mm. For mounting larger diameter sensors (up to a maximum of 18mm), the upper hole of the retaining bracket can be enlarged with a hole. The valve position is visible through the transparent sight glass.

Manual override

The manual override can open or close the valve in the event of an emergency (such as electrical failure or damage to the control valve). The manual override is only available for angle seat valves with control heads Ø 63 and 90.

Manual flow adjustment

With the manual flow setting, the flow can be adjusted from 0% to 100%. In NO versions (normally open), it can also be used as manual override. The flow setting is only available for angle seat valves with control heads Ø 63 and 90.

The control head, available in 3 sizes (Ø 45/63/90), can be rotated 360 °. Due to the angle seat valve body, high flow rates can be achieved with low pressure drop. A great media resistance is given. The angle seat valves are also suitable for high temperatures and vacuum applications. ATEX versions (EX II 2 GD c TX) can also be found in our assortment.
