Type 74CS Angle Control Valve

Actuator Choice

SchuF can provide a full range of actuator types- manual, pneumatic, electrical, hydraulic, or gas-over-oil


Cast Yoke

These guarantee a robust and reliable actuator-to-body connection


Full range of seal-to-atmosphere options

All possible packing-ring materials can be provided, as well as further options such as live-Ioaded packing and leak-detection systems


Stem Lubrication

Available on request


Cast Body

Material selection entirely to customer requirements. The sweeping-angle body geometry provides constant media flow acceleration to the seat


Control Disc with Spindle

Providing maximum control performance and exceptional corrosion and erosion resistance utilising ceramic trim


Blast Tube

This will provide seating for the disc along with optimal flow control. Material such as Hexoloy will outperform ceramic and metal superalloys for strength, hardness and corrosion resistance


Seating Sleeve

Designed to perfectly mate with the customer’s mounting/installation point, leaving no dead-space

Type 28KS Ram Drain Valve

Optional Mounting Flange

A bespoke pad or mounting flange can be supplied for complete dead-space free installation


Sealing Faces

A selection of hard-faced sealing surfaces are available for high-performance, Iong-Iife service


Ram

Designed to perfectly mate with the seat and vessel- with fully hardened, diamond-polished surface to extend packing life


Body Material

Cast or forged material selection (e.g. Duplex, Hastelloy, Titanium, or other superalloys)

Full range of seal-to-atmosphere options

All possible packing ring materials can be provided, as well as further options such as Iive-Ioaded packing and leak-detection systems


Cast Yoke

These guarantee a robust and reliable actuator-to-body connection


Actuator Choice

SchuF can provide a full range of actuator types- manual (with or without bevel gearbox), pneumatic, electrical, hydraulic





Type 50 Y-Globe Isolation Valve

Actuator Choice

SchuF can provide a full range of actuator types- manual, pneumatic, electrical


Cast Yoke

These guarantee a robust and reliable actuator-to-body connection


Full range of seal-to-atmosphere options

All possible packing ring materials can be provided as well as further options such as live-Ioaded packing, pressure-seal and leak-detection systems


Cast Body

Optimised-flow body design provides a low pressure-drop. Material selection according to customer specification


Ram or One-Piece Disc/Spindle

The Type 50 can be provided with a ram or a disc-with-spindle design (shown here). The disc design can also incorporate dead-space-free back-seat sealing, and disc-grinding is a further available option to clean the valve seating area. Tight shutoff to ASME Class VI or API 598 can be achieved.
