Introduction

KV Controls supplies the V-TYPE 1000/2000 Series—a double-offset (high-performance) butterfly valve range for compact isolation and smooth control. V-TYPE 1000 serves Class 150, while V-TYPE 2000 serves Class 300 duties. The series follows API 609/ASME B16.34 design practices and supports actuator-ready top mounting for clean automation packages.

What “double-offset” buys you

The disc shaft is offset from the seat and body centerlines, so the disc “cams” away from the seat—lowering seat friction and operating torque, reducing wear, and helping maintain tight shutoff over many cycles. The seat/packing architecture supports bi-directional zero-leakage soft seating with low fugitive emissions.

Key capabilities at a glance

Pressure classes: Class 150 (V-TYPE 1000) and Class 300 (V-TYPE 2000)
Sizes: typically DN50–DN1200 (2″–48″)
Seat types: PTFE/RTFE/UHMWPE soft seats (zero-leakage design); fire-safe construction available
Design & test practices: API 609 / ASME B16.34 design lineage; API 598 / ISO 5208 pressure tests referenced across the range; API 607 / ISO 10497 fire-safe certification available
Automation: ISO 5211 top mounting for direct pneumatic/electric actuation

Construction features engineers care about

Anti blow-out stem and robust gland stack for packing integrity; two-piece gland flange for even 360° compression
Soft-seat portfolio (PTFE/RTFE/UHMWPE) for tight shutoff and chemical resistance; fire-safe package meets API 607 / ISO 10497
ISO 5211 drive for clean actuator mounting; standard quarter-turn compatibility

Typical applications (South Africa focus)

Chemicals & petrochemicals: fluids requiring corrosion-resistant seats and fire-safe assurance
Pulp & paper / water & wastewater: low-torque isolation in large diameters
Power & industrial utilities: compact Class 150/300 shutoff with automation

Quick selection guide

Confirm pressure class
Class 150 → V-TYPE 1000; Class 300 → V-TYPE 2000.

Pick the seat for the medium & temperature
PTFE/RTFE: broad chemical compatibility, low torque.
UHMWPE: abrasion-tolerant soft seat option.
Fire-safe (API 607/ISO 10497): hydrocarbon service and areas with fire risk.

Decide the end connection
Wafer/Lug/Flanged available across V-TYPE; choose per piping standard and maintenance philosophy.

Size the actuator correctly
Use KV Controls’ torque/selection data and apply service factors (media, ΔP, safety). KV Controls will pair pneumatic/electric actuators and smart positioners to spec.

Need help? KV Controls can run the duty case (ΔP, media, temperature), consult the torque charts, and deliver a valve-actuator-positioner package sized for your worst-case scenario.

Why specify V-TYPE via KV Controls

Integrated automation: ISO 5211 valves + pneumatic/electric actuators + smart positioners (single source)
Fire-safe assurance: API 607 / ISO 10497 certification available
Local support: selection, sizing, commissioning, and spares in South Africa (fast response, lower lifecycle cost)

FAQ

Is V-TYPE available fire-safe?
Yes. API 607:2010 / ISO 10497:2010 fire-safe certification is available on applicable configurations.

1000 vs 2000—what’s the difference?
V-TYPE 1000 = Class 150, V-TYPE 2000 = Class 300. Both are double-offset, high-performance designs.

What sizes can I order?
Commonly DN50–DN1200 (2″–48″) depending on configuration; talk to KV Controls for specific trims and end connections.

Can I mount actuators directly?
Yes—ISO 5211 top mounting simplifies pneumatic/electric actuation.

Which soft seat should I choose?
Soft seats available include PTFE, RTFE, and UHMWPE; KV Controls will match the polymer to your medium and temperature.
