SPIRA-TROL 2-Way Control Valves standard K Serie (EN / ASME)
SPIRA-TROL is a two-way control valve with a single seat and the option to install a cage according to EN and ASME standards. The valves are available in 3 different materials and from DN15 to DN300 (1/2" to 12"). When used in conjunction with a pneumatic or electric servomotor, modulating or on/off control is possible.
Diameters and connections:
See datasheet
Material housing:
- Carbon Steel
- Stainless Steel
- Cast Iron
SPIRA-TROL Valve Characteristics options:
- KE and KEA: Equal Percentage (E) Suitable for most modulating controls, provides good control at all flow rates.
- KF and KFA Quick Opening (F) For on/off applications.
- KL and KLA Linear (L) Mainly for liquids with constant differential pressure across the control valve.
Important note:
Throughout this document, the KE valve is referred to. With the exception of the valve characteristic, KE(A), KF(A), and KL(A) are identical.
