Issue
S-E L2SV Linkage Kit and S-E L7SV Linkage Kit compatibility with Satchwell Plug and Seat Valve Bodies.
Environment
Satchwell 1 series Plug and Seat 2-port and 3-port Valve Bodies.
Satchwell 2 series Plug and Seat 2-port and 3-port Valve Bodies.
Satchwell 3 series Plug and Seat 2-port and 3-port Valve Bodies.
Satchwell 7 series Plug and Seat 2-port and 3-port Valve Bodies.
Cause
Use the correct S-E Linkage Kit with Satchwell Plug and Seat Valve bodies.
Resolution
1. Observe specification number of Satchwell Plug and Seat Valve Body
Generally where a Satchwell AL series Linear Actuator is fitted to a Satchwell plug and seat Valve Body, the Actuator may be replaced by an equivalent S-E Forta or MV15B series Linear Actuator and appropriate S-E Linkage Kit.
It should be noted however that neither the S-E L2SV Linkage Kit nor the S-E L7SV Linkage Kit will enable an S-E Forta or MV15B series Linear Actuator to be mounted on a Satchwell 7 series MZ/MZF or a Satchwell 7 series VZ/VZF plug and seat Valve Body.
The internal screw threads of the Neck Adaptors included in the S-E L2SV Linkage Kit (880 – 0124 – 000) and S-E L7SV (880 – 0126 - 000) Linkage Kit are compatible with the external screw threads on Satchwell 1, 2 & 3 series Valve Body necks only.
The external screw threads on Satchwell 7 series Valve Body necks however differ to those on Satchwell 1, 2 & 3 series Valve Body necks.
Consequently neither the S-E L2SV Linkage Kit nor the S-E L7SV Linkage Kit will enable an S-E Forta or MV15B series Linear Actuator to be mounted on a Satchwell 7 series Valve Body.
A S-E Forta series Linear Actuator may be mounted on a Satchwell 7 series Valve Body however using Linkage Kit 880 – 0135 – 000. No equivalent Linkage Kit is currently available for use with the MV15B series Linear Actuator.
The Satchwell Valve Body series may be determined from the Valve Body specification number stamped on the Valve Body Identification Collar, where the single middle digit of the specification number denotes the series.
In the case of a Satchwell 7 series Valve Body for instance the single middle digit of the specification number will be the number 7 (e.g. 626 – 7 – 402)
